Most of our hole features are cut with our table cutter, so a fractional dimension style is sufficient. On the oher hand, we have a lot of holes that need to be machined, and that means 3- or 4-place decimal dimension, sometimes with tolerances.

I would love to be able to switch between dimension formats on the fly, going from a Ø3/8 opening to a Ø1.505 +.002/-.000 machined hole with a right-click of the mouse.

I see it being added as a flyout menu under "Dimension type", with the Dimension command active. The available styles would be the same as the active styles in the Ribbon bar.
