I just watched a video about Rhino 7’s SubD and I noticed one common case that also happens quite often with 3DS Max polygon modeling. Check this video at the 3:02 minute where the focus is on a bunch of corner faces that are basically where the control polygon has a 90-degree transition:
I wonder is there a tool in SubD that could merge edges to other adjacent edges, so that this particular model gets transformed into the following shape? Also, is there a “Bridge” tool between faces in SubD already? At 7:05 minute of the video I saw that there is a “Bridge” between holes, though. Will the faces need to be deleted in order for the “Bridge” tool to work?
