Knock out mask

#1 06-17-2008, 07:31 AM

This is a really simple thing that I should know how to do...!

But can someone please explain how I can paste a mask onto an object and have
it remove anything underneath it on the layer below to leave a transparant area.

Ie. If I have a square 100x100 and want a 'hole' in the middle of it that
allows any lower layers to show through, how do I paste a circle onto the
square to achieve this.

Thanks!

Create the circle above the square, fill it with white, select both items,
then Modify>Mask>group as mask.

Hi Jerry,

Thank you very much for your reply. Unfortunately this doesnt quite achieve
what I want - the way you described leaves me with a circle filled with the
color of the square. What I want to be left with is a square with a circle 'cut
out' of the middle of it which layers behind it can be seen through the hole.
Any ideas how to achieve this?

Thanks!

OK, you use the same technique: put the circle on top of the layer you want
to see, fill it with white, select both, Modify>Mask>Group as mask. You
should now see the layer as a circle. Now make your square, and put the
circle on top of it.

Alternately, you could make your square, make a circle on top of it, select
both, then Modify>Combine paths>Punch, which will give you the square with a
hole in it - put this on top of the layer you want to see.
