Creating modular piece parts

You can set options on a piece part to use with a CAD model in NX. You can map these options to an associated expression in NX that determines the geometry of the part; for example, you could map the Width option to the geometry of the door. When you create a variant item, Teamcenter copies the model (UGMASTER dataset), and automatically sets the option value to the associated expression value in NX, for example, Width = 500. If you design the door assembly module of the refrigerator freezer as a modular assembly, having a different component for each width and height of door, this could lead to a very large number of components for each size of door. It is more efficient to design the piece part for the door itself as a module, with options for width and height. The variability is then catered for by the variant items, which are created on demand as required, without needing to modify the parent door assembly module to add components for every new size of door.
