Hello!

How we can get name of a driven dimension?
If we try to edit it we get this message:

we may use this driven dimension do define something else and thus see its name.

Or we may temporary make it non driven (what is the correct term: "genera", "main"?) but we may get another problem that does not allow begin editing too:
and it seems to be a perverted way to fix this over defined problem.

P.S. and in this attached file in Taped Hole 1 position sketch there are two dimensions one is driven  and second is set to it. but they are not equal !  May be one can understand why.

Thank you!
