Hello - probably 90 % of these can be fixed by retrimming a surface or the face in a polysurface.

  1. SelBadObjects (Isolate)
  2. Assuming these are polysurfaces, ExtractBadSrf (Isolate again)
  3. usually this will help: DupBorder, UntrimAll, then Trim with all the border curves.
    You’ll want to verify that Joining back to the parent polysurface keeps things valid. If not, use the Check command and see what it tells you… we might need more surgery.
