Identify related roof surfaces from triangulated geometry

[ergo.pikas]

Dear All,

I have been working on triangulated surfaces to re-construct the building geometry from the Estonian national digital twin system. I have got stuck at the point where I need to identify groups for different roof surfaces. I would like to find a strategy for situations like the one indicated in the figure below.

Thank you!

Hi @ergo.pikas ,

Just groupbykey …

The problem is that it is a triangulated mesh geometry. Here is the file with the example geometry:
Kredexi 10 hoonet LOD 2.rvt (7.0 MB)

That is, it is not possible to just group.

Hi @ergo.pikas ,

Have you tried the GroupByDistance node from the springs package?

@ergo.pikas , hi

so work with generic models… hmm
