BIM solution Wall Reinforcement got another update – one which had been Number 1 on our Precast Concrete users’ wish-list: the ability to automatically place fabric sheets of rebar. This feature lets Autodesk® Revit® users model sheets much faster than previously was the case.
Like the other features of our Wall Reinforcement Revit tool, the Fabric Sheets feature is flexible and easy to set up. You can choose your fabric sheet type and define all parameters available in Revit, like sheet alignment, Lap splice length, etc.
What’s great about the fabric area configurations is that you avoid the headache of having to enter additional offset values for each fabric area. Drawing the boundary for the fabric area boundary is also automated to match the shape of your wall layers, which is essential if you have sandwich walls with wythes of different heights.
Dimensioning rebar depends on company standards or on requirements coming from the manufacturer. Either way, it’s relatively easy to do once you’ve got the rebar modeled in Revit®.
One way you can do it is by placing dimensions and changing visibility settings using native Revit commands. Another way is to automate that process with a Revit plugin. For precast elements, I would suggest Smart Assemblies, as it can create views, dimensions, schedules, and sheets – everything you need for shop drawings.
Alright, so I will skip how to do the process manually in Revit, which hopefully is covered on YouTube or by your Revit software providers, but here is how you can do it with our tools. I will jump straight into the Smart Dimensions tool that’s part of Smart Assemblies and open its configuration. (Video below.)
1. Open Smart Dimensions
Once you’ve opened Smart Dimensions, go to its configurations.
In this post, I’ll show three ways for placing joist pockets in Revit for tilt-up construction projects.
One way to do it is manually in plain Revit. The other two ways make use of our Smart Connections BIM tool that can distribute hardware, details, voids, any sort of element or family in Revit whether you’re designing buildings from precast concrete, wood frames, or metal frames.
Whichever way you go, the first several steps are the same, so let’s start there. (Video below.)
STEP 1. Create a pocket family by using a face-based family template.
Modeling main reinforcement and stirrups for precast beams in Revit is easy with our Beam Reinforcement tool. Some clients recently gave us feedback regarding the add-on, so we developed some new features that will further streamline the work of precast detailers.
The updates have to do with stirrups, rebar at beam ends, and common bending shapes of main bar. Descriptions of each of those new features below.
Revit rebar placement: Centered stirrups
After one of my previous blog posts about Revit beam stirrup layout, a user contacted us asking for a small improvement – centered stirrups – because in some situations it is better to have equal spacing than to have bars at exact positions.
Smart Walls is our Revit add-on that simplifies wall management, allowing you to quickly disassemble layers into different wall types, control gaps and joins, split walls into panels, insert gravity points, and more. Part of our Tools4Revit Suite, it’s also included in our Precast Concrete BIM Solution since wall panels are ubiquitous in precast design.
This latest update for our Smart Walls tool has new ways of splitting walls horizontally – via configurations – and vertically – via reference plane.
Where do we get the ideas for continually improving our BIM Solution for designing precast in Revit? From top professionals around the world. We enthusiastically welcome user requests and build their ideas into the software to make the life of structural engineers, drafters, and modelers easier.
From Finland to Florida, from California and Canada over to the Netherlands and Norway, from India to Illinois, from Sweden and Estonia down to Australia — users send in their requests for software updates that would make their work smoother and more efficient. That’s where the action’s at. User-feedback helps us continually enhance Precast Concrete with new features that others in the precast design industry can benefit from as well.
So, at the close of Revit Year 2021 and the outset of 2022, here is a summary of all the features that were added to our Precast Concrete BIM Solution during the past year. We go through each of the tools that comprise Precast Concrete and look at the improvements that were made to each.
Although our Smart Assemblies BIM tool already had ways of showing dimensions of rebar, more flexible options were needed for dimensioning rebar in assembly views. That’s mainly due to the fact that we’ve added some robust reinforcement tools for Revit to our portfolio.
This latest update of Smart Assemblies brings to bear the power of our well-known dimensioning technology – Smart Dimensions – so that you can automatically measure rebar in views. It takes a load of manual tasks off your plate, eliminating a lot of mouse-clicking so that you have more time to focus on real design tasks.
You can see few of the features applied in this video. Read in more detail about each below.
This feature of our Smart Assemblies tool has been around for several years already, but I’d just like to remind our existing users about it and show it to Revit users who are new to our Precast Concrete design software. Because this is a tip that can really help you save a lot of time by avoiding a lot of inefficient, boring clicking in Revit.
If you want to create individual piece tickets for precast concrete walls in Revit, your best option is to go with assemblies because they have separate views, schedules, and information about each production element.
The downside: Working with assemblies can be quite a pain if you use Revit out of the box.
Here’s an example with precast sandwich wall panels. In my test project I drew a couple of panels in different directions and created assemblies with Revit. Revit creates the assembly origin, which gives information about view directions.
Below you can see the axes of the origin, the green arrow being the direction of the front view. Notice that the orientation of the origin for most of the wall assemblies that I have created below is wrong.
Ever wondered how to make grid lines appear in assembly views in Revit?
By default in Revit, grids are only visible in model views. So, to remedy that, we spiffed up the shop drawing configurations of our Smart Assemblies add-on.
Now there’s an option to show grid lines in assembly views if they cross your element in the model. It works with different categories, and grids can go in both directions. All you need to do is to select ‘Insert Grids’ in the far right column of the Shop Drawing Configurations window for the views that you would like to see gridlines on.
