Companies can load variant specifications in Windchill to create new and update existing variant specifications using a command-line utility that can be run from a Windchill shell.

You can also use this application to load a variant specification to create new variant part structures, or update an existing variant part structure based on the updated variant specification.

The input data is provided in a spreadsheet format. The input spreadsheet specifies all information required for creating variant specifications and variants: the configurable part and option set information, characteristics of part and rule configuration specification, and a set of initial choice selections for the Option Filter.

Alternatively, you can load variant specifications by calling an out-of-the-box API.
