Hi Guys: Another puzzling behavior by Sketchup. So, I have a drawing of a plate with holes. I decided I need to change the size of a couple of holes. I drew new hole outlines and deleted the old hole outlines. Sketchup then proceeded to fracture the face of the plate into a hundred little triangular shaped areas instead of one are the size of the plate. Don't understand why this happens. It has happened to me several times in the past as well. Only way to get out of it is to revert to an earlier save before the edits. ***? What is the proper way to edit the size (diameter) of a hole without frakking up the surfaces on which the hole is placed?
