Hello,

I am a beginner with SW and I am trying to model an X-Acto Knife. I am having trouble with the grip on the handle. The grip is a helix or spiral that overlaps in a clockwise and counterclockwise pattern. I have tried the swept-cut feature and hit a geometry error wall I have also tried swept-boss and had the same result. Please see the attached file with errors.

Preferable I would like to sweep-cut to achieve this grip pattern. Can someone please demonstrate how to achieve this effect with no errors? I have put a link to a picture that shows the grip pattern. http://i.ehow.com/images/GlobalPhoto/Articles/5154382/264684-main_Full.jpg

Please let me know if you need more information.

Thank you
