I use Omnigraffle a lot for wireframing. I'd often like to be able to just draw a straight line in a position of my choice. I don't want the line to connect to anything. How can I draw a straight line exactly where I want it, without having to connect it to other objects? Whatever I try, it always seems to only let me snap to existing objects rather than just freely draw a line wherever I like.
