We're trying to modify the way tolerance is shown to make it easier to check. We would like to show the nominal dimension and the actual tolerance limits next to each other. As a simple example, instead of 20.0 +/- .5 as a symmetric tolerance or 20.5 / 19.5 as a limit tolerance, we would like to show 20.0 (19.5-20.5).
The idea is that in a more complicated example, you don't have to actually add or subtract to check if a part is in the tolerance because the actual range is listed. You'll be able to cut a part to the nominal and then check the limits to make sure the part is acceptable.
