Boolean Operations

[sgoswami]

I would like to make a shape defined by a subtraction of two shapes. Eg. A rectangle with a hole in it. Ideally, I would like to draw the rectangle, the circle inside, and then 'subtract' the two, so that when I hatch this it gives me a rectangle with a hole. How do I do this?

QCAD does not work with surfaces but with lines, arcs, circles. A rectangle for example consists of four lines.

To hatch a rectangle leaving a circular island inside, please proceed as follows:
1. Draw rectangle
2. Draw circle inside
3. Select rectangle and circle
4. Menu: Draw -> Hatch
5. Choose pattern in hatch dialog and click OK
