I am using 64bit Windows XP, SolidWorks 2008. I want to dimension from the edge of a hole to the side of the part (not from the centerpoint). In 32bit Windows, it works fine to hold the Shift key down and it will grab the arc rather than the center point, but when I try to do the same thing on this 64bit machine, once I hold down Shift, the edge does not appear to be selectable. Anyone else have this problem?
