Specifying the Names of CAD Documents
By default, the Windchill file name of the instance CAD document is a combination of the configuration name and the extension of the model, configuration_name.model_extension. The file name of the generic CAD document matches the name of the SolidWorks model file.
For example, if the Configuration name is config1, the Windchill instance file names are as follows:
config1.sldprt for a part
config1.sldasm for an assembly
