I have not been able to find an answer to this problem--maybe someone has run into it before.

I am creating some drawings that require the display of diameter dimensions in detail views where the full diameter of the part is not displayed.

The 2.035 dimension shown is easy--just pick on the line, the diameter is recognized and placed, and then hide the dimension line to the right.  However, some of the diameters do not display as lines, e.g., the angled corner above needs two corners to recognize the diameter, and the opposite corner does not appear in the view to select.  Anyone know how to do this?

Thanks in advance.
