Tolerance Rounding
For the secondary units of dual dimensions, you can set the limits of the secondary unit’s tolerance range to fit within the tolerance range of the primary unit by using inward rounding so that the dual dimension does not conflict with the primary dimension.
Click . In the Dimensions node and in any of the nodes under Dimensions, click Tolerance. In the Dimension Tolerance dialog box, under Dual dimension tolerance, select Inward rounding of secondary unit tolerance extents. When selected, if the high end of the secondary unit’s tolerance rounds to a number that is larger than the displayed rounded number of the primary unit’s tolerance high end, the secondary unit’s high end is rounded down. If the low end of the secondary unit’s tolerance rounds to a number that is smaller than the displayed rounded number of the primary unit’s tolerance low end, the secondary unit’s low end is rounded up.

Additionally, in any dimension PropertyManager, on the Value tab, you can select Inward rounding to control individual dimensions.
