Hi,
I am having a problem with grasshopper not recognising certain type of BREP’s being closed.
The issue occurs always when two parts of one BREP meet each other just at the corner.
(see images below)
In grasshopper these Breps are called open. An open Brep should have naked edges but instead there are only non manifold edges.
Interesting. What are you going to do with these objects?
Using for energy simulation and generating 3dprint files.
The polysurfaces seem to be converted from meshes.
Why don’t you stick with the mesh geometry?
That is correct. They are converted from meshes. I am trying to find out the best workflow.
The buildings have to be put together (joined,union) with the ground floor. With “Mesh Union” i do not have very good experiences.
But apart from that I think the problem described above would be nice to be solved.
What about ShrinkWrap the buildings and a base and then split to fit the printer size?
Clean better your meshes before converting them to breps. Use Align + Combine&Clean.
You have a lot of non-manifold edges. Edges are not aligned. etc etc
Please attach your starting meshes.
