Rebar along path

Revit
1

Hey everyone,

I need to reinforce complex shape that is not covered by standard Revit 2026 tools:

So I decided to place one instance at the beginning of the instance and the multiply it by dynamo.

The problem is that when i use node “Select model element” then I can not find a way to copy the rebar instance… It is not standard family and I can not manage it.

Do you have any ideas? Thanks.

This feels like something f which could be populated by the standard tools… can’t confirm or help without the model (or a similarly failing one) though.

Hi Jacob!

Unfortunately we can not handle it by standard tools. Infrastructure elements are in multiple curves and spirals and this is making a lot of issues.

  1. Varying rebar set is kind of useful but it is perpendicular always to the start plane and in the end we are getting something like that:

  2. Path or surface reinforcement needs surfaces to be connected but in most cases this is imposible:

  3. I can not use array due to complex alignment.

I wish it was possible by standard tools but Revit is not for complex infrastructure(for now)…
So I decided just to draw one bar at beginning of the element and then multiply it by dynamo perpendicular to any edge. I made everything else but I can not manage to copy the element…

I found kind of solution…

  1. I did not manage to work with ElementTransformUtils.CopyElement and Rebar type…

  2. I put the bars in model group and then I was able to copy it. Its too slow and complicated idk if its the only way.
