Writing formulas for validation conditions

A validation condition formula specifies the parameters for a validation requirement. The formula relates to the expression stored in a given NX part.

In NX, you can run a requirement check on the part for validation against a selected requirement condition formula.

The requirement check references the requirement condition formula and maps it to the part expression.

You can use arithmetic functions, operators, and symbols as well as numbers and variables.

For example, the following requirement condition formula limits part dimensions:

l + 2*w + 0.9*h < 200[mm]

In this example, the variables for the formula are defined in millimeters as l (length), w (width), and h (height).

You enter condition formulas in the New Requirement wizard.
