Those &*$^#& extra/hidden faces!
I'm using 6.5 and I seem to be having a problem I haven't had previously. When I extrude faces, I get hidden faces under whatever I'm extruding. I then have to go delete all of them, which is very time consuming. I think this all happens because vertices/edges aren't merged by default when I extrude. I know this because when I extrude several edges at once, I get heavy border edges along the extrusion (as opposed to clean geometry). I then have to merge vertices and/or delete extra faces every time I extrude.
Surely there must be a setting somewhere in "Preferences" I am missing, or some other relatively simple solution to my problem. In the past, I've been able to just extrude faces and edges without these problems. Can anyone help?
Thanks in advance!
