This is driving me insane. I’ve attached a blend in which I am trying to cut the intersection of circles out of a plane. I’m using the Boolean modifier and trying all variation including intersect etc but nothing good happening. I’m following the tutorials to the letter but still no good. Anyone know what I’m doing wrong?
See demo here for your blend file http://screencast.com/t/xccNjmMAptQl
YOu should also clean your mesh up. Why are your objects so large, you are getting clipping in the 3dview. Also reset the scale values back to 1 (Ctrl+A / scale) to prevent further problems.
