How to control maximum value for an expression in NX?


For e.g. 


 There is an expression X = 25mm. 


And I would like to predefine the maximum value that users can set for X is 30mm.


How can I set that?

Solution

For this case, the user can add a check to validate the values of expressions.


The steps:

1. Right click on expression X in Expressions dialog->Add a check
2. Click New Requirement
3. Enter any name for the requirement
4. Select "Definition Method" to "Single Sided Comparison"
5. Set <= 30
6. Now if the user enters any value greater than 30, it will be indicated as 'Check Result= Failed"  in Expression dialog
