> I create a BSPTree from a BoundaryRep (Brep) my test Brep is a cube as represented by
a float array containing 8 3D points in(x,y,z) order and an array of indices (12 triplets
for the 12 faces of the cube). I construct a BSPMesh() as shown in the code below. I can construct
the PolyhedronsSet() but have problems extracting the faces from the BSPTree to reconstruct
the BRep. The attached code ( shows that a small change to 1 of the vertex positions
causes/corrects the problem.
> Any ideas?
