I've recently downloaded Qcad after trying other drawing software and not being able to get on with them. Qcad certainly meets my needs and is very user friendly. The last time I mucked about with CAD was 15 or so years ago on Auto Cad. So with some trepidation I will rise to your drawing challenge.
I have a couple of questions though.
1. Is there an 'array' option f the central circle of 'bricks' or is it move/ copy?
2. Is it possible to copy from one layer to another, deleting the selected entity from it's original layer?
Thanks in advance.
