Revit allows structural engineers to create their models and documentation in an advanced BIM environment. By using Revit, structural designers and engineers can produce accurate design intent models and give engineers and detailers the information they need to develop models to a higher level of fidelity for Fabrication and Installation purposes.

Dynamo for Revit is a visual programming interface that allows engineers to use computational methods to design organic and optimized buildings and structures faster than with traditional modeling tools.
Dynamo allows users to create, associate and analyze multiple building parameters that revise their designs automatically. Engineers can then iterate and evaluate design options with ease, and build structures based on natural and mathematical principles.

In Revit software, the physical model and the associated analytical model are created concurrently. The physical model of the structure is used for coordination as well as documentation. The analytical model is used for structural analysis and design. Structural loads, load combinations and boundary conditions can be easily added to the analytical model.

Through interoperability with Autodesk Robot Structural Analysis Professional, as well as various 3rd party analysis tools, Revit helps to extend BIM to structural Analysis.

Structural Analysis for Revit enables structural engineers to conduct analysis in the cloud as a part of the BIM process, and helps minimize disruptions to workflows as users continue to design as analysis is completed.
Performing cloud based analysis from within Revit with the Structural Analysis service helps to streamline the design process and provide analytical results early and often to inform design intent.

5 great features in Structural Analysis for Revit

Revit provides streamlined process from design through detailing to fabrication by supporting the easy modeling of steel connection details and 3D reinforcements.  For steel frames, Revit offers streamlined interoperability with Autodesk Advance Steel detailing software through Steel Connections for Revit. With over 130 parametric connections, Steel Connections for Revit allows engineers and detailers to coordinate more effectively by exchanging more accurate design deliverables for steel fabrication.  This results in more precise detailing, estimating, and reduces errors in fabrication and installation.

The post Revit for Structural Engineering appeared first on BIM and Beam.

Last year I published a blog post contemplating the value of BIM for Concrete, and discussing how the next generation of BIM tools for reinforced concrete are helping our customers in four main ways. I described these BIM-centric concrete benefits as:

1. Combines the versatility of 2D documentation with the higher level of fidelity and accuracy of 3D modeling of steel reinforcement and concrete accessories, with minimal effort to produce both.
2. Allows users to design and detail with clash prevention in mind to reduce clashes both in the preconstruction and site execution project phases.
3. Enables the transition from design to detailed models while respecting both perspectives, following local code requirements, and automating the process of making changes so they are less disruptive to the design process.
4. Increases transparency and quality of the model information being used from bidding to procurement by not only providing quantifiable information, but also enabling access to it in collaboration friendly environments.

I must say that it was great to hear your feedback from my last post, and see that so many of you are as excited by the future of concrete as I am! I’d like to continue the conversation I started with you, and spend some time discussing these four benefits and what they mean for the industry in depth. And by “in depth” I mean this in an engineering sense—I’m going to be thorough.

Since there’s A LOT to cover, instead of writing one long blog post on concrete that might bore you to sleep, I’m going to focus on one benefit at a time. For today, let’s talk about the benefits realized when moving from 2D to 3D.

Benefit #1: The BIM-centric concrete solution combines the versatility of 2D documentation with the higher level of fidelity and accuracy of 3D modeling of steel reinforcement and concrete accessories, with minimal effort to produce both.

We hear often that moving to 3D-based rebar design requires more work than traditional drafting. Many believe that creating a spatial representation of the engineer’s design intent and later installation reality is an extra step added to the effort related to drawings production. This is often followed by the complaint that obvious benefits of 3D (clash avoidance, accuracy, etc.) are for the benefit of general contractors rather than designers and detailers.

I want to challenge this.

While it’s true that 2D drawings, shop and lift drawings are still the primary deliverables nowadays serving as means of communication and instruction across broader teams, we’re also seeing these trends as well:

• For communication, project teams across the are globe driving towards model-based communication and information handover, especially when it comes to the Design to Detailing transition. Customers like Norconsult are already using this approach effectively.
• As a means of instruction, an undisputable benefit of traditional 2D detailing is the speed of drawings production and versatility. But the downside is the lack of precision leading to rebar clashes on site, compromises on quantities, and coordination with the formwork model.
• Design changes also require drawings to be reproduced. The lack of consistency surfaces easily as drawings can be “adjusted” (“faked”, honestly speaking) and ultimately lose their connection to other sources of information like BOM, model data, IFC, ERP, etc.

Drawings and 3D rebar detailing in Revit

Let’s assume for a minute that by using a BIM-centric approach to rebar detailing we can still maintain a highly efficient and versatile process for drawing production, and incorporate the precision and information completeness that comes with 3D modeling at no additional cost. Well, that’s the idea for Revit.

For Revit we want to bring these two benefits of 2D to 3D together. How? This is where rebar detailers can leverage the traditional approach and perform 2D detailing “in canvas” of a section, plan or an elevation view taken directly from the concrete model, and have the rebar model created “for free” in the background. You can see this illustrated in this example:

Then, as the design/detailing evolves to a point where coordination is needed, detailers can focus on the rebar model editing directly and more comfortably in the 3D views. While in the 2D drawings space they can just easily add tags and dimensions to the rebar as a downstream part of the process since rebar is there, placed accurately, already.

What then makes a real difference is the accommodation of changes in the BIM process; there is no need to re-model or redraw rebar when that happens. The below example shows again how changes of concrete object sizes or rebar distribution parameters make all the rebar information adapt to changes and the submittals update instantly. Talk about a benefit for the detailers and designers!

A glimpse of the future

The ultimate proof of BIM-centric and fully model based reinforcement detailing efficiency can be recognized for projects dealing with complex concrete geometries such as water treatment stations, industrial structures, buildings with complex architecture, etc. Anywhere humans struggle to visualize the 3D structure in their minds when communicating instructions with only 2D drawings.

There are examples where using 2D drawings as layout instructions is nearly impossible. Check out this groundbreaking use case from Norconsult who is implementing a fully paperless process to construct this large hydro plant in Norway.

Additionally, use of these modern methods applied for complex projects is presented in a very interesting and recent master thesis from Pål Røe Larsen (Technical University of Denmark, Kongens Lyngby). Larsen’s thesis (you can download it here) includes several case studies and interviews with adopters from the industry, and draws attention to the new future of the concrete industry.

So, what do you think? Are you using a BIM-centric modeling approach for concrete yet? Are you seeing these benefits already? Stay tuned for more on this topic and let me know your thoughts in the comments.

For my next post, I’m going to talk about what I’ve described as benefit #2: allowing users to design and detail with clash prevention in mind to reduce clashes both in the preconstruction and site execution project phases.

The post Sofistik Reinforcement Detailing 2018 is Available appeared first on BIM and Beam.

A reinforcement drawing shows the positions of all reinforcing elements in a particular structure or a structural element. There are numerous ways of drafting concrete shop drawings, and drafting styles vary between countries or even between design companies.

Rebar in Revit comes with properties that can be read by predefined tags (families) created specifically to read the rebar settings. It’s possible to let Revit tag these items automatically, or you can manually tag the items.

Multi-rebar annotations significantly improve rebar detailing workflow. A multi-rebar annotation allows you to tag multiple rebar and rebar sets with a single annotation.

You can use these multi-rebar annotations to tag each bar in a rebar set with a detailed annotation for fabrication and construction.  Thanks to this functionality, drawing creation becomes quite smooth and productivity increases incomparably.

If you want to use this functionality in Revit you need to go on the Annotate tab -> Tag panel and under Multi-Rebar you can find the following two tools:

• Aligned Multi-Rebar Annotation
• Linear Multi-Rebar Annotation

Once you run one of them then you simply select rebar sets or individual rebars to have them annotated by one single annotation.  You can also modify multi-rebar annotations like other tags.

A Multi-rebar annotation family is a Revit system family. In the Type Properties you can find a tag family and a dimension style that can be easy configured and adjusted.

The post Multi-Rebar Annotation in Revit appeared first on BIM and Beam.

A new type of Rebar can be modeled in Revit 2018.1, by working in 3D views and selecting the structural element faces to which the rebars are aligned.

Free Form Rebars can have any geometry, either planar or 3D, and can be used for modelling and detailing of reinforcement in complex 3D structural elements.

Rebars are created at the cover distance from the intersection of the references that the Revit user selects. One reference can be made up of one or more structural element faces.

The Surface Distribution rebar type consists of bars that transition between the Start Surface and the End Surface and are distributed along the Host Surface.

Free Form Rebars are part of the Structural Rebar category, and have all the properties associated with it. Free form Rebars can be created as single bars or rebar sets, rebar quantity for every instance of a Free Form Rebar can be easily adjusted.

Then the rebar constraints can be managed using in canvas tools in 3D views to provide enhanced and accurate rebar placement.

You can use customizable numbering settings and provide accurate shop drawings with schedules that display varying lengths in Free Form Rebar sets to better drive fabrication.

This new functionality increases 3D rebar modeling versatility and helps you define the accurate reinforcement for non-standard shapes of concrete elements.

Autodesk brings into play a new automated workflow for the precast concrete industry. The Autodesk Structural Precast Extension for Revit 2018 is a BIM-centric offering for modeling and detailing precast elements that promotes productivity and precision for engineers, detailers and fabricators working on typical building projects in the precast industry. As an app for Autodesk Revit software, Structural Precast for Revit provides Revit users access to powerful tools for automatic rule-based segmentation, reinforcement, shop drawings and CAM files generation of precast planar concrete elements. The app is available on the Autodesk App Store.

Leveraging the concept of Parts, which support the construction modeling process by letting you divide certain elements from the design intent model into discrete parts, the app provides the opportunity of having one single source of truth for various personas that need to work with the model. This way, designers’ and fabricators’ perspectives are respected and various Levels of Development can be displayed – two key benefits of embracing a Revit-based workflow for Precast projects.

Based on predefined parameters in the “Configuration” dialogue box, you can specify the rules that will help drive the automated workflow downstream from Design to Fabrication. First up, the elements are automatically segmented and fitted with connectors, lifters and bushings. All of these are actually Revit families, so customization is easy. Reinforcement is also done automatically and you can define multiple patterns, based on fabric sheets or rebar sets. There is even a tool that creates Custom Fabric Sheets, where each wire can have its own diameter, length and distance with respect to the adjacent wires. This is useful both for optimizing the rebar consumption based on structural analysis and for minimizing clashes with various MEP equipment that might be embedded or going through the panels.

Speaking of embeds, the app comes with another tool that automatically adds to the corresponding precast assemblies all the electrical sockets, cable ducts, extra rebars or any other kind of component that is in the model. This way, the precast walls and slabs will contain the logic that is required for fabrication, minimizing much of the hassle in the factory or on site.

One particularly powerful tool that Structural Precast for Revit offers is Automatic Shop Drawings. Once the company’s standards related to drawing style and content are embedded in the drawing templates, for each precast element the drawing is created, with all relevant views and bills of materials. If required, multiple shop drawings for each assembly can be generated; for instance, one showing the reinforcement and one highlighting the position of the embeds. It’s also worth mentioning that this Automation tool can be used with company standards for all elements at once, all elements per submittal or per element.

And because we are working in Revit, coordination of the precast model with Architecture and MEP comes as a natural benefit. In the highly likely event that changes need to be performed to the precast elements (we all know change is a daily routine in the construction industry) you don’t have to worry: the precast elements, shop drawings and bills of materials are automatically updated—helping to keep information up-to-date.

When Fabrication is ready to start, with just one click, the creation of CAM files is done. Both Unitechnik (versions 5.2 and 6.0) and PXML (version 1.3) are supported. The various file naming options and output settings offer flexibility to generate these deliverables simultaneously in a swift and tailored fashion.

The product is mostly suitable for typical building projects, made up of slabs and walls produced in factories with a high level of automation. Currently, three types of elements are supported by the new app: Solid Walls, Solid Slabs and Hollow Core Slabs.

Of course, we need to remind ourselves that it’s not only about design and detailing, but also about construction coordination, planning and execution. And that’s when I recommend you to export the Revit model to Navisworks Manage and BIM 360 Team. Or, if you are in the position to meet with your customer and walk him or her through the details of their future building, why not do it in Revit LIVE, so she/he can view, better understand, feel and experience it before it is being built?

With Structural Precast for Revit, Autodesk makes a notable step ahead for the future of automatically making structural things with this new precast concrete design software tool. So go ahead, try it, and let me know your impressions around it.

Before we move into the Dynamo part let me quickly highlight rebar numbering and partitioning in Revit.

In Revit, numbering allows identical reinforcement elements to be matched for schedules and tags.

Partitioning in Revit gives you the ability to define a common parameter for reinforcing elements within a certain construction sequence. Rebar elements are automatically given a unique number within same partition based on their type, shape & geometrical parameters.

Partitioning for reinforcement identification serves a number of organizational purposes depending on how a building is designed or how it will be constructed. Any rebar, rebar set, or fabric sheet instance in a model can only be assigned to one partition.

The number for a rebar or fabric sheet instance as well as its partition may be viewed in the Properties palette under Construction.

You can use the Reinforcement Numbering dialog to make adjustments to rebar numbering sequences.
Using this dialog you ran quickly and easily rename your partitions and renumber rebar elements within a specific partition.

The Minimum number of digits for reinforcement numbers option specifies the minimum number of digits to display in a sequence. For example, when set to 3 digits; rebar number 2 displays as 002.

The Remove Gaps option becomes active when one or more gaps exist in a sequence. The checkbox removes gaps in the numbering sequence of rebar and fabric sheets in a partition.

This is a very convenient tool to manage rebar numbering however sometimes we need apply some specific, more sophisticated rules for how our rebars should be numbered. This is a common problem for many structural detailers.

For example, let’s image a situation where we would like to have all rebars numbered within the same partition from the shortest rebar to the longest one…

If you have already started thinking how you could do this in Revit, I have to tell you to stop. This is an instance where Dynamo for Revit comes in handy and is the right tool at the right time!

Let me show you how helpful Dynamo is for this issue.

I made a few assumptions:

• In my Dynamo script I want to select all rebars from a specified partition automatically (this is so there is no need to select any rebars in my model).
• All rebars from the given partition will be renumbered from the shortest rebar to the longest one.
• I want to be able define a starting number of the shortest rebar.

Because the Rebar Number parameter is read-only, first I need to create a project parameter which I call “New Rebar Number” and then I end up with the following Dynamo script:

As the first step I need to select all rebars from a partition I specify.

Next, it’s time to get information about the lengths of my rebars. Even though my project is metric I need to make a units conversion to have them presented in millimeters rather than in feet.

Knowing lengths of my rebars, now I am able to sort the list of rebars by lengths.

… and finally it’s time to renumber the rebars:

Now I can create a rebar bending schedule based on the New Rebar Number parameter!!

A few weeks ago I published an overview video for Autodesk Structural Precast Extension for Revit and now I think it is the right time to get up to speed on the latest Precast tools in Revit.

With this post I would like to start a dedicated series on this new app to help you get started with the tools and to share with you some useful tips and tricks.

Autodesk Structural Precast Extension for Revit 2018 was released along with Revit 2018.1 release.

The extension must be download from the Autodesk App Store and then installed on the top of Revit 2018.1

…or you can also access the installer from within the Autodesk Desktop App:

At this moment, the extension is available in English, French and German languages.

Once installed, several Revit families and templates are placed in a dedicated location… C:\ProgramData\Autodesk\Structural Precast for Revit 2018\Families\en.

The installed files include:

• Annotations
• Custom slabs (sample slab families)
• Mounting parts (lifters and other connection parts)
• Profiles
• Revit (rebar shapes)
• Symbols
• Title blocks

Here is what the Precast tab looks like once the extension is installed.

You must be wondering what the On/Off button does, an answer is pretty straight forward as it enables or disables the extension. You can use this tool to turn the extension off to replenish hardware resources and improve Revit performance if there is such need.

When you attempt to run the first command, you are presented with the following warning:

This is basically saying some content needs to be loaded for this extension to work properly.

That’s why it is a good practice to start working on a new project running the Configuration tool first.

Before you start using Structural Precast Extension for Revit you should configure these settings for walls, slabs and built in parts. The settings include position numbering, part information, segmentation rules, reinforcement definition, and project drawing defaults for walls and slabs, as well as settings for annotation and dimensioning in parts.

Once you open this dialog and click OK all necessary Revit families and templates will be loaded to the current project automatically and the warning message will not be bothering you anymore.

The Configuration dialog is organized in a tree view, each node contains options for precast concrete assemblies.

For example the wall node configures settings for solid structural walls. These settings include wall part information about lifters, bracings and connectors:

…segmentation rules:

…reinforcement definition:

…and project shop drawing defaults:

The similar groups of setting you can find for slabs (solid slabs and hollowcore slabs):

The Built in parts node configures settings for annotation and dimensioning in parts and the CAM Export node configures additional data specific to each CAM file type.

All these Precast settings are project related but you can maintain consistent configuration settings across similar projects by exporting them to an XML file which can later be imported into other projects. This gives you the ability to create different configurations for different manufacturers or sites.

To export/import your current configuration file just right click in the tree view and select Export/Import from the context menu.

In my next post of this series I will touch upon the topic of segmentation of walls.

New Precast Content

New Precast families for beams, columns, slabs, and foundations are now available.

Revit users can choose between various types of I-shape, T-shape, trapezoidal and many other beam cross sections. Columns having different corbels configurations and top supporting conditions for beams have been created. TT slabs and isolated foundations, both block and sleeve, are also part of the new Precast content.

The extended range of parameters that control their geometry allow for faster and more precise modelling of Precast concrete structures.

The German version of the families is based on Fachvereinigung Deutscher Betonfertigteilbau specifications.

The content is localized in English and German and can be downloaded from the Autodesk Knowledge Network.

This new content allows users faster and more precise modelling of Precast concrete structures.

Rebar Content Update for France and Germany

New French and German rebar shapes have been added to the Library, to enhance rebar modelling.

Among the French rebar shapes, we have also included the ones according to the older French code NF P 02 016:1993, which many French customers use throughout their projects.

The German library has been too updated with three shapes, again, to offer a complete range of rebar shapes used in this region.

The new content can be downloaded from the Autodesk Knowledge Network.

This provides enhanced rebar modelling to support better local standards.

This article is the continuation of a conversation that I started with the blog post depicting the value of BIM for Concrete and continued with from 2D to 3D with rebar detailing. If you’ll remember, I’ve described what I see as four main benefits for a BIM-centric approach to concrete:

1. Combines the versatility of 2D documentation with the higher level of fidelity and accuracy of 3D modeling of steel reinforcement and concrete accessories, with minimal effort to produce both.
2. Allows users to design and detail with rebar clash prevention in mind to reduce clashes both in the preconstruction and site execution project phases.
3. Enables the transition from design to detailed models while respecting both perspectives, following local code requirements, and automating the process of making changes so they are less disruptive to the design process.
4. Increases transparency and quality of the model information being used from bidding to procurement by not only providing quantifiable information, but also enabling access to it in collaboration friendly environments.

In this post, I want to focus on benefit #2, and discuss how leveraging rebar clash-detection for concrete can benefit both the preconstruction and execution phases of a project.

Benefit #2: The BIM-centric concrete solution allows users to design and detail with rebar clash prevention in mind to reduce clashes both in the preconstruction and site execution project phases.

There are many practical reasons why having rebar clashing on a construction site is highly undesired, causes serious project delays and therefore significantly increases project cost.  This can easily happen in seismic regions when large diameter rebar are used and it is not possible to resolve clashing issues by just adjusting bar shapes on site or when rebar distribution needs to be very dense as typically required for power station structures. More examples can be uncovered.

When a clash is detected, an intervention (change order) is typically sent to detailers as the finding still comes late in the design to construction process.

Clash detection tools like Navisworks can help in such situations, detecting clashes in cases where a rebar model is delivered in 3D earlier than when rebar are being fabricated and installed.

Definitely, best is when a detailed definition of rebar layouts comes already correct from rebar detailers. There are several enablers helping rebar detailers be successful and deliver clean and precise instructions for rebar fabricators and installers. Let’s name these opportunities:

Precise positioning and coordination with other objects

Precise rebar placement mechanisms mentioned above and software intelligence can guide detailers to define rebar positions with respect to all geometrical boundary conditions; both 2D and 3D snapping, increment based guiding, non-overlapping positioning with regards to rebar radiuses and diameters works as a desired clash prevention.

Setting rebar for clash-avoiding behavior

More importantly, Revit rebar objects are born with certain intelligence respecting logic that detailers can define for it. For example, this means that we can set up rebar to behave in order to keep right distance from concrete faces, right distance from other rebar, being still adjacent to each other when rebar diameter changes, or adjust redistribution in function of changing sizes of concrete hosts, etc.

The implanted behavior makes rebar respecting detailers intent and therefore avoiding clashes as they are created and when model changes come into play.

(Imposing constant distances for rebar in Revit)

What we see is what we get

As simple as it sounds, seeing rebar cages in three dimensions and with realistic sizes greatly increases a detailer’s perception and understanding of proposed reinforced concrete configurations.

Unlike with traditional shop drawings where each perspective needs to be presented in a separate view, as rebar cages are defined in Revit we can see the whole rebar cage in a single 3D view, manipulate with it, see it from all angles, and in context of adjacent model elements. All while authoring.

(Dynamic 3D view in Revit)

Early review and 3D model inspection

Having a broader 360 perspective with more than a single pair of eyes is usually the recommended method to secure quality for any task, rebar detailing included.

It’s amazing how easy it has become lately to share model information for a review with others.

Simply sharing the Revit model through BIM 360 makes it available via a simple link for stakeholders for inspection / review / commenting / comparison of changes. Exposing a proposed solution to others before it’s locked and stamped as rebar detailing submittals greatly increases the quality of the detailed fabrication and installation recommendations and therefore, again, makes it clash free oriented the moment it leaves a detailer’s room.

(Screenshots from a web browser containing BIM 360 viewer)

All in all, the clash-free rebar reality is the result of a few factors: technology enablers, a detailer’s attitude, and yes … if a contractual clause specifies it as a requirement.

The post BIM for Reinforced Concrete – Rebar clash prevention appeared first on BIM and Beam.

In this post of the Structural Precast series I would like to touch upon the topic of segmentation of precast walls.

Segmentation of precast walls can be done automatically or manually. Before we run the automatic segmentation we should check and adjust the Configuration Settings.

The Configuration settings can be imported or exported via XML files to easily share the rules across several users, working on the same or different projects.

On the Part Tab we set up Lifters, Bracing Inserts and Connections. Here we decide what types of elements will be used and their positions within precast assemblies.

All the connections and built-in parts are Revit families and can be customized according to the project’s requirements.

On the Segmentation Tab we define rules for splitting based on fabrication, transportation or other functional requirements.

To execute a segmentation of walls we need to select all the walls and press the Split command. During this command, the precast wall assemblies are created. Lifters, bushings and connection are created according to the rules from the Configuration settings.

Just after the wall segmentation we can see both the original elements and parts that have just been created.

We can display parts only to better review the outcome of the Split.

Switching between different LODs (Level of Development) is pretty easy and fast so we can review the original elements at any time.

As an outcome of the Split command we get wall parts, lifters, bushings and connections grouped automatically into a precast assembly.

Watch video:

When a custom segmentation is performed, it often does not allow for clear mathematical rules and we cannot apply rules specified in the Configuration. At this point we need to perform the manual segmentation of the original walls.

The manual segmentation is performed starting directly from the original, unsegmented element.

First, we need to convert a wall into Revit Parts.

Next, we define a division line or lines. Drawing such division line(s) we can very precisely determine where a segmentation should occur.

Once manual segmentation is complete, the “Split” command can be used to convert the parts into precast assemblies.

Now on this floor we have a mixture of original walls and parts we just created manually.

IMPORTANT TO NOTE: If the original wall is selected, instead of the manually created parts, the manual segmentation is overridden and the wall is segmented according to the Configuration settings. That’s why it’s important to make sure the original element is not selected but only parts.

If one part is still larger/heavier/etc. than the specifications indicated in Configuration Settings, it will be further divided, respecting those rules.

Let’s see the outcome of the segmentation in this case.

Another way we can control the segmentation of elements is by a manual adjustment of parts after the segmentation.

In this case we select a part and edit a position of a division line – this can be done very precisely too. Once the part is updated, the entire assembly and connections, lifters, and bushings are updated as well.

We can also manually adjust a position or a type of individual elements within an assembly. In this case I am changing a position of one of the bushings.

In the similar way, we can update lifters and connections within a precast assembly.

The visual programming interface of Dynamo for Revit is enabling structural engineers with the tools to build structural models with minimal energy and make their own structural design tools.

In the early stages of the structural design structural engineers and designers can use Dynamo for Revit to interpret the architectural model and explore ways to begin their initial structural design.

Basing on the architectural geometry they can retrieve a model data and create parametric based structural models to explore several design options.

Dynamo allows structural engineers to design organic and optimized buildings and other structures faster than with traditional modeling tools, using computational methods.
Structural engineers can use their creativity to develop optimized structural systems using computational logic in an advanced building information modeling environment.
They can access and edit building parameters more effectively than traditional hard coded tools allow. They can iterate and evaluate multiple building design options with ease, and build structures based on natural and mathematical principles.

Using computational logic in structural design with the visual programming interface of Dynamo opens up a new way of interacting with a building information modeling database.
Within Dynamo structural engineers can automate processes in Revit, and build complex and logic structures with minimal energy.

The AEC Collection now extends visual programing and structural analysis offering you Dynamo Studio and Robot Structural Analysis Professional. Dynamo Studio is a standalone programming environment which can help solve challenges faster and improve structural workflows.
Robot software provides structural engineers with advanced structural analysis capabilities for large and complex structures of any type.
The Structural Analysis for Dynamo package allows for parametric modeling and structural analysis workflows in Dynamo and Robot Structural Analysis Professional.

Based on the Dynamo geometry structural engineers can create an analytical model, apply section shapes and boundary conditions such as supports and releases.
Moreover engineers can automatically apply structural loads and one of the benefits of this approach is the fact that values of structural loads are recalculated every time when the structural geometry changes.
When the analysis is done the results can be reviewed by structural engineers in the Robot Structural Analysis environment or they can retrieve the results of analysis within the Dynamo environment.

With the Structural Analysis package for Dynamo software, structural engineers may optimize their existing structural workflows or invent some new ways of doing things which improves their productivity.

Dynamo can improve many other structural workflows, for example:

• It can help structural engineers calculate, generate and apply structural loads to analytical models in Revit automatically.

Learn more

• Structural engineers and detailers can use Dynamo to seed up and automate concrete detailing workflows in Revit.

Learn more

• It can help quickly generate complex structures in Advance Steel.

• and more…

There is a long list of possible use cases where Dynamo helps engineers, designers and detailers in their daily work getting things done faster and with minimal effort. Dynamo users can automate repetitive tasks to speed the design process and improve efficiency. They extend their designs into interoperable workflows for documentation, analysis, coordination and fabrication.

In this post of the Structural Precast series I would like to show you how in Revit we can easily add grout tubes and tubes on top to precast walls.

Grout tube and tube on top are families that come with the installation of Structural Precast Extension for Revit. They are both face-based families. When modeling you can use them or your own families.

In Revit, there are a few ways how these elements could be added to precast wall assemblies.

First, I would like to show you a traditional, manual way.

1. We simply start the Place a Component command.
   
2. Then select a family and a type.
   
3. Next select a wall face. Note: Orientation of grout tubes depends on which side/surface of a precast wall has been selected.
   
4. Then a position of these elements can be further adjusted using built-in Revit capabilities. For example, you can specify a distance from the edge, distance between elements, use copy or mirror tools etc. …
   

As you probably noticed already the process itself is pretty straight forward however it can be very tedious and it takes a lot of time as we need to do the same for every single precast wall instance.

This is a situation where Dynamo for Revit comes in handy. Let me show you my automated process of adding tubes to the Revit model.

I made a few assumptions:

• My Dynamo script should be ready to be use in Dynamo Player.
• It should work with multi-selection of precast walls.
• Input parameters should allow selection of types of elements as well as their precise placement.

As a result I ended up with a Dynamo script with the following input parameters in Dynamo Player:
Let’s have a look inside the Dynamo script. First, I need to retrieve selected faces.

Next, I have to check the orientation of my faces.

My Python script checks if the beginning of local coordinate system of my surfaces is at the top or bottom and it calculates a rotation angle for grout tubes.

Now it’s time to get information about lengths of my wall parts.

Now I have all data needed to calculate coordinates of insertion points for both grout tubes and tubes on top.

My next Python script helps me calculate where insertion points should be located taking into account all input parameters:

And finally I can add these tubes to my Revit model in the right location and with correct orientation. Here I used the Springs.FamilyInstance.ByFacePoints node available in the Spring Node package.

Adding Grout Tubes and Tubes on Top

All nodes:

This automated process of adding grout tubes saves tones of manual and tedious work and save a lot of time.

This is the third blog post in a series that discusses the advantages of working on concrete projects in a BIM process for structural engineers.

Before we dive in, let’s quickly review the four benefits of BIM for engineers:

1. Combines the versatility of 2D documentation with the higher level of fidelity and accuracy of 3D modeling of steel reinforcement and concrete accessories, with minimal effort to produce both.
2. Allows users to design and detail with rebar clash prevention in mind to reduce clashes both in the preconstruction and site execution project phases.
3. Enables the transition from design to detailed models while respecting both perspectives, following local code requirements, and automating the process of making changes so they are less disruptive to the design process.
4. Increases transparency and quality of the model information being used from bidding to procurement by not only providing quantifiable information, but also enabling access to it in collaboration friendly environments.

This post will focus on the “how” of benefit three.

Benefit #3: The BIM-centric concrete solution enables the transition from design to detailed models while respecting both perspectives, following local code requirements, and automating the process of making changes so they are less disruptive to the design process.

Coordinating the design intent model with the detailed model has always been a factor of “bureaucracy,” since historically, structural engineers work with different software than other project stakeholders. Tools to import and export various file formats across software produced by different companies have been used for some time, but we believe simplicity and precision should be a key factor for coordination and will ultimately lead to a strong and reliable behavior of any structure during its lifecycle.

Take, for example, a precast concrete wall. Its length and height are dictated by its place in the building. Segmentation is dictated by engineering, architectural, or fabrication requirements, and its reinforcement is determined by the structural engineer.

Revit-model-driven structural-analysis

Let’s assume a conceptual model is received from the architect. The structural engineer creates the analytical model and structural system. Revit has multiple tools for defining and editing the analytical model, or the model can be exported to various analysis software that are interoperable with Revit – including Robot Structural Analysis Professional – to perform structural analysis. The results can then be imported into Revit and reviewed to understand the impact of various design changes.

With the results now available in the Revit model, the rebar definition can begin. There are two approaches to this process – one for EMEA and the other for AMER.
Firstly, the structural engineer analyses the efforts and proposes reinforcement patterns, a practice typically encountered in North America. The engineer can use engineering schedules or place tags in 2D or 3D views that reference concrete elements and reinforcement patterns. Secondly, rebar can be determined more directly by structural analysis results, while respecting local design codes, a method usually embraced by European countries.
The beauty of Revit is that it allows for both approaches, enabling all structural engineers to work in a BIM environment connected to architects, MEP engineers, and the extended project team.

Code-driven automatic generation of reinforcement

With the “results packages” in the BIM model, code design tools can drive the automatic generation of reinforcement. Multiple types of concrete elements can be reinforced following the engineering design standards from various countries and regions.

SOFiSTiK Reinforcement Generation (RCG) automatically generates a 3D rebar model in Revit based on structural analysis input, and works with concrete beams, columns, floors, walls, and slabs. It follows the defined rules to generate the reinforcement to meet the required reinforcement criteria. Respecting various country or company standards can be done by controlling the rules files. Once the reinforcement is generated, it can be manually edited.

RCG offers real-time checking of the reinforcement directly in Revit 3D views. Using the “Check” command, the required and existing reinforcement in a framing element can be compared. If the reinforcement is adjusted, the diagrams react instantly, giving precise feedback to the engineer about how to optimize the reinforcement patterns.

In a similar manner, the “Check section” command compares the existing reinforcement in user-defined sections of surface elements against the required reinforcement.

Once the rebar modelling is complete, detailing can begin. To comply with the same standards across this phase of the project, the SOFiSTiK Reinforcement Detailing tool can produce customized shop drawings and bar bending schedules.

Graitec Reinforced Concrete BIM Designers is another powerful tool that leverages Revit results packages to generate reinforcement in single-span and continuous beams, columns and isolated foundations. It is compliant with Eurocode 2, US ACI 318-14, and Canadian CSA standards. The various settings allow the use of specific bar diameters and other constructability rules, like the maximum number of bars to be placed in a concrete element according to its width.

The tool also calculates a group of identical elements simultaneously so that they have the same rebar cages, based on the theoretical reinforcement envelope for the entire group. There is also the ability to save reinforcement cage templates which can be applied to similar elements and adapt to their new hosts based on predefined rules.

The app also generates engineering design reports. The content of each design report depends on the country-specific template and can be configured by the user. A fully comprehensive design report describes the theoretical formulas and values used in the calculation process according to the country selected, and includes the results and work ratios for each verification.

Customizable bar bending schedules and automatic shop drawings based on predefined templates can be created using the app’s dedicated features.

CADS RC3D has been designed to enhance the placement, annotation, and bar marking of rebar in 3D structures. The software provides functionality to create 2D detail drawings and bar bending lists to country standards. Features of the app include:

• Annotation functions to detail tapered ranges and mark rebar ends
• Enhanced layering tools to split rebar into zones within a structure
• Editing functions to copy rebar from one structure to another
• Path placement functions to allow the rebar to be placed parallel to another rebar in the structure
• Managing the rebar according to assigned structure, release, and drawing sheet
• Custom rebar lists

One Source of Truth

Given that the above steps can be completed in the same model, it is easy to see the benefit of having one source of truth and using Revit as the single platform for design and detailing.

Since many reviews occur during the design phase, we can expect many changes to the geometry of the concrete elements. Normally, this could lead to significant manual changes to the reinforcement, but because Revit’s reinforcement is constrained to the concrete elements, it means it adapts automatically every time.

And not only is the rebar in-sync with the concrete structure, it can also be modelled in its finest details to achieve a clash-free model, ready to be sent to fabrication and installed on site.

Having always up-to-date and coordinated structural analysis results, rebar models, engineering design reports, bar bending details, bar schedules, and shop drawings will ultimately lead to successful project delivery.

Building on Autodesk’s strategy to make Revit a robust model authoring tool for designing and detailing, the Revit 2019.1 release includes an important update for concrete detailers and engineers that will help to increase modeling versatility, accuracy, and productivity. I am excited to share this new feature with you—take a look!

Free Form Rebars can now be used to create rebar sets with planar rebars distributed along the faces of a structural concrete element and aligned to a distribution path.

Just like with the surface distribution type, modeling of the aligned distribution type can be done by working in 3D views and selecting the structural element faces to align the bars.

1. Simply click the Structure tab > Reinforcement panel > Rebar
   Then select the Modify | Place Rebar contextual tab > Placement Methods panel > Free Form Rebar > Modify | Place Free Form Rebar contextual tab > Distribution Type panel > Aligned
   
   
   Note: In 3D views, the Aligned Distribution of Free Form Rebar placement is launched by default when accessing the Rebar command.
2. In the Type selector at the top of the Properties palette, select the desired rebar type.
   Optional: Select other properties like Layout Options, Style, Hooks, Workshop Instructions.
3. Select the references that define the set. One reference can include one or more element faces.
4. Click the Path option  to define the distribution path.

Rebars in an aligned distribution are created at the intersection of each individual bar plane with the host surface. All the bars are planar, respect the cover of the host and are aligned to the distribution path.

The distribution path is the edge of an element that can host rebar. This can be selected directly when placing the set and represents the intersection of the faces in the Path Surface 1 and Path Surface 2 constraints.

Apart from the references that you input during placement, free form rebar is automatically shortened or extended to the nearest faces that is part of the host. The shortening is done along the bar, while the extension is tangent to the end.

If the option to automatically close bars is enabled, then closed contour geometry can be obtained for each bar in an aligned distribution set. This option is enabled by default when placing a bar with the stirrup/tie style.

The rebars in the set can be aligned to the path (it’s the default option) or can be parallel to the face selected in the align / close constraint.

This new type of the free form rebar distribution increases 3D rebar modeling versatility and helps you define the accurate reinforcement for standard and non-standard shapes of concrete elements.

A few weeks ago I published an overview video for Autodesk Structural Precast Extension for Revit and now I think it is the right time to get up to speed on the latest Precast tools in Revit.

With this post I would like to start a dedicated series on this new app to help you get started with the tools and to share with you some useful tips and tricks.

Autodesk Structural Precast Extension for Revit 2018 was released along with Revit 2018.1 release.

The extension must be download from the Autodesk App Store and then installed on the top of Revit 2018.1

…or you can also access the installer from within the Autodesk Desktop App:

At this moment, the extension is available in English, French and German languages.

Once installed, several Revit families and templates are placed in a dedicated location… C:\ProgramData\Autodesk\Structural Precast for Revit 2018\Families\en.

The installed files include:

• Annotations
• Custom slabs (sample slab families)
• Mounting parts (lifters and other connection parts)
• Profiles
• Revit (rebar shapes)
• Symbols
• Title blocks

Here is what the Precast tab looks like once the extension is installed.

You must be wondering what the On/Off button does, an answer is pretty straight forward as it enables or disables the extension. You can use this tool to turn the extension off to replenish hardware resources and improve Revit performance if there is such need.

When you attempt to run the first command, you are presented with the following warning:

This is basically saying some content needs to be loaded for this extension to work properly.

That’s why it is a good practice to start working on a new project running the Configuration tool first.

Before you start using Structural Precast Extension for Revit you should configure these settings for walls, slabs and built in parts. The settings include position numbering, part information, segmentation rules, reinforcement definition, and project drawing defaults for walls and slabs, as well as settings for annotation and dimensioning in parts.

Once you open this dialog and click OK all necessary Revit families and templates will be loaded to the current project automatically and the warning message will not be bothering you anymore.

The Configuration dialog is organized in a tree view, each node contains options for precast concrete assemblies.

For example the wall node configures settings for solid structural walls. These settings include wall part information about lifters, bracings and connectors:

…segmentation rules:

…reinforcement definition:

…and project shop drawing defaults:

The similar groups of setting you can find for slabs (solid slabs and hollowcore slabs):

The Built in parts node configures settings for annotation and dimensioning in parts and the CAM Export node configures additional data specific to each CAM file type.

All these Precast settings are project related but you can maintain consistent configuration settings across similar projects by exporting them to an XML file which can later be imported into other projects. This gives you the ability to create different configurations for different manufacturers or sites.

To export/import your current configuration file just right click in the tree view and select Export/Import from the context menu.

In my next post of this series I will touch upon the topic of segmentation of walls.

New Precast Content

New Precast families for beams, columns, slabs, and foundations are now available.

Revit users can choose between various types of I-shape, T-shape, trapezoidal and many other beam cross sections. Columns having different corbels configurations and top supporting conditions for beams have been created. TT slabs and isolated foundations, both block and sleeve, are also part of the new Precast content.

The extended range of parameters that control their geometry allow for faster and more precise modelling of Precast concrete structures.

The German version of the families is based on Fachvereinigung Deutscher Betonfertigteilbau specifications.

The content is localized in English and German and can be downloaded from the Autodesk Knowledge Network.

This new content allows users faster and more precise modelling of Precast concrete structures.

Rebar Content Update for France and Germany

New French and German rebar shapes have been added to the Library, to enhance rebar modelling.

Among the French rebar shapes, we have also included the ones according to the older French code NF P 02 016:1993, which many French customers use throughout their projects.

The German library has been too updated with three shapes, again, to offer a complete range of rebar shapes used in this region.

The new content can be downloaded from the Autodesk Knowledge Network.

This provides enhanced rebar modelling to support better local standards.
