Hi all - How can I manage the normal of a specific SudD surface in other to control its direction in most cases? With the backface color turned on, I am unintentionally encountering normal discrepancies, which cause errors when offsetting SuD Surfaces in non-uniform directions, I’ve tried “Dir” or the sub-options in “ExtrudeSuD” but they do not work. I think that until now, Rhino has lacked a dedicated Normal command for SubD ( Providing only “UnifyMeshNormal” for meshes). Anyway, Is there anyway to solve this situation?
Hi @wim , it happens to me too, but I’ve never managed to save a set of geometries to reproduce the problem. (doing Undo trying to replicate never trigger the problem again..)
I’m not sure if this is the same as Kien is describing, but for me sometime doing SubD bridge and/or adding a single SubD face or simply joining (maybe even while “reflect” symmetry is active) results in a SubD object with incoherent normals.
Usually I use ExtractControlPolygon and UnifyMeshNormals and back to SubD, but it doesn’t work all the times…
