I am adding a view for clarification. I would like to do a
blow up of one edge, have an overall dimension thats a reference
and the leader lines are broken. I have attached jpgs to show what
I am getting and what I want.
The only way I've found to show that type if forshortened
dimension is in a broken view. The way I do what you are looking
for is to take the dimension you have shown and hide the upper
dimension/extension lines(RMB selection).
