I have a long, rectangular poly which ends up "folded" by 180 deg (not necessarily in half, as in the pic). After folding, this poly is obviously very non-planar. I want to add a new "crease" edge along the fold line to fix it. I can create the edge manually in the viewport, but I want a procedural SOP solution. The Divide SOP seems most logical (Convex poly: ON, Triangulate non-planar: ON), but it doesn't always work. Sometimes it creates a new crease edge, sometimes it doesn't (maybe because folding by 180 deg is so radical). Is there a SOP that would reliably do this? I see a "Crease SOP", but it doesn't create edges, it assigns weights to existing edges. PolySplit SOP could work, but the way you need to specify the split points (% of edge length etc) seems unnecessarily complex. I do have the 3D point positions of the fold line, so I can easily create a line there. But how do I "plug" it into the existing poly as a valid new edge?
I apologize if the answer to this is somewhere obvious--through Googling I've found some of people asking this over the last 15 years, but no answers that work. I have a model that I need to crease before subdividing. Manually selecting the edges is impractical--too many round buttons with flat tops. How can I automatically select/group just the edges joining faces with right-ish angles? I've tried the "include by edges" and setting min and max edge angles, but that doesn't appear to do anything unless you chose "Edge Angle Uses Angle Between Edges," in which case it selects pretty much everything. Thanks!
