I know I can hold down shift to drag a line constrained to 45° or 90° with the pen tool in illustrator. However, I'd like to see the line previewed interactively as I draw. I can get that behavior with the line segment tool, but need multiple segments linked together. Is there a way to do this?
(Obviously one option is to draw all of my segments individually with the line segment tool and then join them together, but then I have to do a lot of post-hoc adjustment to the joins if I didn't line up the ends perfectly in the first place.)
