SW automatically places a double arrow on foreshortened dimensions. SW also offers a list of arrowhead style options if one right-clicks on an existing dimension arrow. But the double-arrow is not among those options. Is there any way to manually edit an existing dimension to show a double arrow that is actually part of the dimension? I am embarrassed to admit that in the past I have simply placed a separate arrow symbol right next to an existing arrow. Clunky and stupid. Surely there is a better way.
