thanks, that helped

I got another question, I don't know if you have run into this, but everything is all square, except the surface that the subs are on. this is angled. Now, the prob that I'm having is when I make the circle for the sub, I try to remove that circle, but it doesn't seem to disapear? I tried a square, then a circle on a flat area of the box, and it seemed to work just fine, i could see right inside the box, but not when I try on that angled section. Any idea?
I would post a pic, but I don't know how to save it so that I can open it with a different program....how do you save it so that I can post it like yours?(sig)
