Dual Dimension Tolerance

[looslib]

Is there anyway to force NX to give smaller values for a dual-dimensioned in/mm dimension tolerance so the mm size will never exceed the in size?

Example: 4-3/16 +/- 1/16 inches
106.4 +/- 1.6 mm when using convert tolerance
Max size is 4-1/4 (4.2500) BUT using the mm, you have 108 which is 4.2519.

If NX truncated the secondary tolerance, then it would be 1.5mm and the max would be 107.9 = 4.2480.

Has this issue ever been discussed by anyone's company or by the Siemen's development/marketing team?

I think I am following you ... The best work around for you may be to:

Dimension style > Units > untoggle "convert primary tolerance to secondary units"

then work with the tolerances from there

I am in NX6

Yes, we are aware of the manual workaround. This also requires you to manually set the tolerance for the secondary units.

If the system truncated instead of rounded on the secondary tolerance values, the part could never be built outside the primary tolrance band. The way it is now, a part built to the secondary units can go outside the primary range.
