Problem with SubD

sketchup

#1

Hi there,
I created a basic 3d object from 2d views and tried to smooth it out using SubD. However I seem to have gotten these kind of ‘wrinkles’ in places. These fade as i increase the sub divisions but i cannot seem to get them to go away entirely. I’ve experimented with the crease tool but with little success. Any help would be very much appreciated!
I’ve attached some screen shots and my file.

You need to learn about quad faces (faces with 4 edges and no more and no less). It’s a reasonably large subject, but not so difficult. Get thomthom’s ‘quadface tools’ plugin too… amongst others…

I think i realise what has happened. I remember reading that SubD works best with quadfaced models. Thanks for your reply!
