I want to be sure that I'm using sketch techniques efficiently.
I'm making a sketch. In my part I have a rectangle in a landscape orientation. I want to sketch a rectangle right below it, with the original rectangles bottom edge coincident with the new rectangle's top edge. The new rectangle should have the same height as the old one, but a width that is one quarter of the original rectangle's width.
How do I accomplish this efficiently? (As few mouse clicks, no hard-coding numbers, etc.)
