Boolean and S Drill
 

Alright im tryin to cut out an object out of another one nad it goes all funky. Like if i do a square out of like a bigger square it works. But if i like try to do a square out of soemthing slanted it doesnt come out right!!! Can anyone help me!

Thanks

Can you possibly post a screenshot showing us what you mean. It might help us put some sort of response together for you...

Most likely your object is more than slanted, it's non-planar. If you hit 'w' in polygon mode the list will tell you if you have non-planar polygons. If you do, then mystery explained. Bools and stencils always get defuncitated by non-planar polys.

If you have non-planar polys then you either need to triple them first, then try it, or model the shape so it does not become non-planar in the first place.

If you don't have any non-planar polys then do what Mark said and post us a screen capture. And seek the advice of people smarter than me.
