How to cut a circle from a square?

Question

CorelDRAW

Good evening! I'll try to explain the essence of the issue, for example, there is such an image

. It has a background (square) and a figure inside it (circle), you need to make sure that the circle is not on top of the square, but cut out of it, that is, not just a drawn circle, and a round void inside a square.
This is done for screen printing on glass, and you need to "explain" to the computer that there is nothing in place of the circle so that it does not fill it with white paint.
How to do?

Answer 1

Corel has such a panel Formation

That is, you need to draw a square, a circle on top of the square and subtract the circle from the square through the formation menu (there are several ways, for example, using the Back minus front or Exclusion tool ). Do not understand - write.
The resulting object will be exactly what you are asking for. For example, if you engrave this sketch, the center (circle) will not be engraved.

Answer 2

Is this drawn in photoshop? If so, it's very simple, select the circle and press del. The main thing is that the zero layer is transparent.
