Just imagine you need to run simulations to verify your fitts,
so you always need to adjust the sizes of your parts, because for a drawing you just need to place a dimension with the settings of a fit.

For example like this:

But for the Simulation you need to have the size of the fit.
In that case the dimension is 50 H8/s7, so you need to make the hole between 50.000 / 50.039 mm and the shaft 50.043 / 50.068 mm.

To get now min and max stress you need to run at least two studies

Or what would you say to a new option within the "Contact Set..." like "Fitting".

Once you activated it, you just need to select one face of the fit contact and adjust the settings

As a result it would be great to get min, max, mean, ....

I'm looking forward to your comments
