How can i disable the double sided extrusion to 1 sided extrusion. It seems i got stuck with 2 sided extrusion (both symmetrical and non-symmetrical) no matter how i click.
The symmetric and non-symmetric double sided extrusion icons are toggles. You should notice that whichever one you used, it should be highlighted (activated). Click on it again and it will go back to the non-activated colour. Let me know if this is clear enough for you.
