I have three adjacent closed breps.
However, I’m unable to get the two interior walls as shown below:
The three breps are defintely overlapping over those two interior walls because if I bake the breps into Rhino and use solid union to join them, those two surfaces will be removed as shown below.
I wonder what is causing this issue… and I have several other groups of breps having the same problem.
Appreciate your kind suggestion. (GH file attached)
