I use rotating the page as the way to estimate angles:
-
Rotate the page
-
Do a couple ghosting motions
-
If angle feels off then rotate the page again
-
repeat this once or twice to get the angle almost perfect
-
ghost once or twice
-
execute line
Making a complete box becomes just a matter of rotating the page in the right directions. I look at the part of the box that's drawn so far to tell how much to rotate the page.
