Setting expression values

Modular variants support the capability to set an expression value in NX from an associated option value in Teamcenter; this capability is not available in classic variants. Make the association simply by ensuring the expression name in the NX part is the same as the option name on the item module; the UGMASTER dataset for the part must be defined in this item module. You can use options to set any expression. In a piece part, you typically use expressions for geometric parameters such as length or the number of elements in an array of features. In an assembly, you typically use option values to control position, for example, by determining the parameters of a mating condition such as the linear or angular offset.
