Problem: "Can input plus value for Minimum Variation(lower deviation) of dimension."

Solution Ideas: "1) edit the property of dimension
2) select Tolerance type:Limit in Dimension Tolerance dialog
3) can't input plus value for Minimum Variation
PS:
I think that this is a common design error for CAD software, because deviation or tolerance rule is specified by the following rule.

1)Minimum Variation is less than Maximum Variation.
2)Minimum Variation either is plus, or is minus, zero.
3) Minimus(Maximum) Variation is called as Lowwer(Upper) Deviation specified by ISO."
