Hi Jim,
this is just my opinion. I would like to hear other people and more from your difficulty.

If an element on the drawing is vetorial, there is no chance of mistakes when dimensioning.

The snap function may catch an other element, close to the right one. Hatches, for example, do it. If so, try disabling layers view.
