I'm working on Adobe Illustrator CS6 and I've a question about how to cut an area from a shape using another shape. To clarify the point, I've the first image below.
What I want to do, is to 'cut' the circle shape from the rectangle, so that the rectangle will have a centre transparent hole; image (2)
And of course, if I change the background, it'll look like image (3)
Thanks in advance
