Another Dynamo story: Reinforcement that “can’t” be done…..Part 1/2

From the inaugural RTC event until now I have had great chat and conversation with my friend Håvard Vasshaug, and one of the things we discussed about was reinforcement modelling with Revit. It started with a particular shape for a wall he was discussing about in his excellent RTCNA class.

Havard wall

From this point, I started thinking on how this could be achieved. Håvard suggested a solution with Adaptive Component, this is cool and can be done. manually…..

As I was on a good learning curve with Dynamo, I tried to automate AC placement. See the result in this post. Far from perfect, but a good start to believe this can be done in the end.

Later on, and further with Dynamo, I’ve discovered that the structural framing could be another good solution: it answers the need for modeling, and upon everything it provides schedules. It also provides a better batch processing to lower the memory needed to proceed. Let’s go kids.


This is what you will see in this video:

The definition used here is available for download here; you will also need the package named “UV/XYZ Grid From Face”, courtesy of Andreas Dieckmann . This definition works with the latest build of Dynamo available from here, and the Rebar-SF family is here.

The points to remember are:

1- select a face

2- evaluate UV grid on this, and remove the points on the edges

3- make curves in both directions

4- use the curves to place Structural framing families

If you are lucky enough to attend both AU2013 and Håvard’s class there, you may know this video already ;-).

More to come in another post about Dynamo and reinforcement.

    Using a Structural Framing family for this looks like a great workaround. But what about taking into account cover settings?
    And even more critical, what if you need a bending schedule, with specific the bending shape figures. Do you guys have advices on that, maybe using dynamo? Personally, I’m mainly struggling with that one, and don’t want to use the API for it…

      Hi Dieter. Cover setting is set for now with the offset of the SF families. but I work on it, to make things coming from Dynamo.
      About the bending, I don’t think it could be described as the “rebars” are bend in different planes. On a construction site, I would design a template in wood or stell coming from the shape, to help workers placing the rebars.
      Here it is more a question of Intended model for REO and scheduling quantities.

    This looks cool, i am thinking to try out Dynamo. Being as an Architect one thing always comes first. How to fabricate !!. If technical resources for fabrication are limited. Besides does dynamo has the capabilities to produces shop drawings for complex structure.
    One more question, in reference to this post.How structural stabilities are checked.
    Please help me to figure out before i try Dynamo.

    Dynamo works on top of Revit. no problem for most of the shop drawings you will need.Structural instabilities will have to be checked in Robot Structural analysis or like.

    Did you get further with your reinforcement placing? I am placing rebars in a retaining wall drawn in true elevation and coordinates, and have placed the stirrups but I am having trouble with the grids on face since my NurbsCurves aren’t planar. Have you been able to work around that? Your blog entrys have helped a lot.
    p.s. Which node is it you use for framing? I cant find a node with exactly this input and output … I have used the StucturalFraming byCurveLevelUpVectorAndType.

    Hey Julien,

    Great post and a really cool video. I am looking to model walls like that myself.

    I tried to use the Dynamo-file, but it dosnt seem to work for the latest version of Dynamo. Do you have a newer file or can you help me in anyway to make the cool stuff that you do? 🙂

    Helga, this was done in the previous release of dynamo, obsolete today. This workflow is a demonstration of possibility with dynamo, but has to be updated seriously. And for me it is totally out of topic right now. go on, success is at the end of the road!!
