I have a confusion when creating the face.
wall_edges = 
next unless item.is_a?(Sketchup::Edge);
ents = Sketchup::active_model.entities; gp = ents.add_group; fc = gp.entities.add_face(wall_edges);
the exception is thrown, indicated that “Edge has different parent”
what’s going on? anyone can afford help, please?
thanks a lot
