extra faces after extrusion
Hoping this is just a noobish oversight on my part. When I extrude an edge inward along the face I am creating a new and shorter face. For example if I create a cylinder and want to extrude the top edge inward to hold the top...it creates new faces along the top, so two layers of faces. Its fine if I want say to have the center open, I can just delete the full faces. But if I want to use that on the cylinders top as a holding ring then I cant erase the original faces.
I get same behaviour anytime I extrude edges on any shape inward along the original faces, double layers.
