Have you ever had a small dimension where the text was bleeding into the arrowhead? With multi-function grips you have the option to flip the arrowhead to the other side of the dimension extension line. I use this feature all the time.
Select the dimension and hover over the grip at the end of the dimension line. When the menu appears, select Flip Arrow.
Notes from Cadalyst tip reviewer R.K. McSwain: A nice tip and one of several things you can do in this same manner. See also Tip #3599.
