Dear Thomthom,
I was playing with SubD with this model, when I couldn’t get it to subdivide. quadissue.skp (29.9 KB)
I named it a quad issue because I thought I was not creating all faces as quads, so I was going to post it in a related thread about that, but praps it’s linked to this thread more… dunno.
I got Heisenbug by trying to create this as a solid, and downloaded solid inspector 2 just now to try to rectify the problem. As an experiment I know that there are edges which share more the one face (the small ‘box’ and the ‘big box’ but I thought that I could make crease certain edges (the common ones to both ‘sections’) to solve this…
Hope this is vaguely helpful…
I’m aware of the other thread about solids, but this is about the ‘Heisenbug uncertainty principle’ so it should stay here I guess…
