Say you have 2 holes you want spaced 20 +0.4/+0.2 mm apart, is there any way to dimension this in such a way that the drawing will show the dimension and tolerance as stated, but have the holes in the model be positioned 20.3 mm apart (nominal + mean tolerance)? Not all CAM software is able to read tolerances and average them out, but designing everything with symetric tolerances is also not ideal.
