I wanna check if display dimensions in the drawing file show the exact value of the dimension, or if the value has been changed/overridden by other users.

I used the API get_ShowDimensionValue() and GetOverride() to check all dimensions.

It works well on normal dimension but hole callouts (The results of "hole callouts dim"->get_ShowDimensionValue() is always True).

My question is:

How to determine display dimensions (Including hole callouts and other types of display dimension) show the exact dimension value or not.

Thanks in advance!

Environment: VS2005, C++, SW2010SP0.0, Windows XP
