Hi! I am trying to interpolate a face with Skin Contours (Fredo6’s Curviloft toolbar) but the tool didn’t detect the edges perfectly. Changing Vertex Matching or Simplify didn’t help. Usually when I click on created surface, there appears additional floating window showing the connections and I can add some forced pairs. But sometimes, like in this case, I cannot change the geometry. ![skinning](https://global.discourse-cdn.com/sketchup/original/3X/d/b/dbd1cc175a4aa3ad859a6297df5dcbc6c1e1a73e.png) Another issue with adding forced pairs is that sometimes when I succeed with adding but I don’t like the result, I want to “Redo last change” and that change doesn’t redo. ![curviloft - undo nie działa po Add forced pair, forced pair się nie tworzy](https://global.discourse-cdn.com/sketchup/original/3X/5/f/5f5141afb973ba94acf0eb65d0d18f4f9a815303.png) So the problem is actually double, within Skin Contours. In the first case I’d like to do exactly what I’m doing in the second one. Any ideas why these things happen and if it’s possible to fix them? ---
