Originally posted by Eldwick If you select the edge and the edges around and apply a "Full Crease" you can achive a perfect sqaure: I'm fairly sure this can lead to undesirable results when you have a geometry like Turbo Dan is working with. If you do a full crease in an otherwise uncreased area, you can end up with glitches in the smooth areas - at least that was my experience HTH MrR
