hi I'm a new user of autocad. and I will use it only to design very simple mechanical drawings
so my questions is better illustrated iwth a simple example I create a square of 10 inches edge. I draw two circlels in it.
now I extrude the square to a cube (10x10x10). then I want to have the circles to become holes one starting from the bottom surface and entering the cube for 1 inch. and the other hole starting from the top surface and entering for exmaple 2 inches into the cube.
My problem is that all the elements are on the bottom surface and when I extrude I always extrude starting from the bottom. is there a way to have one element positioned on the top and extrude from there negative? I would like to find a way to make this more convenient than moving the object physically with the mouse.
hope I was clear enough claudio
