Hi All!

I’m working on a script to route conduit automatically through steel-framed walls.  
I’m trying to get the curve (sketch) of the openings in a structural column, which I’ll use to create a possible path for routing.

Everything I’ve tried so far has yielded only partial results - one hole instead of the existing 4.

I’ve attached a sample file with one column, and a .dyn with my attempts so far.

Does anyone know how to select these openings in Dynamo? Maybe even just their location points?

Thanks!

Hi,

You can obtain the outline curves of the openings like this :
