What I want do, for example, is copy the bottom rectangle, taking it's bottom right corner as base, and paste it 200mm to the left of the top left of the other polygon. That is, I want to place it 200mm on the direction of the temporary extention snap line. But everytime I try to do it, the second rectangle will just be placed 200mm in the direction my cursor is placed. There's some way to set draftsight to work how I'm expecting?
