To Use Spec-Driven Piping Library with PTC Windchill
1. In the Creo Parametric Options dialog box, set the allow_import_file_extension configuration option to ptd, imp.
2. Import the ptd and imp files into workspace using the embedded browser.
3. Check the .ptd and .imp library files into the common space.
4. Set the values for the configuration options to the path in Windchill common space where the libraries are checked-in.
 
* When the piping design utilizes the ptf and inf files, these files will not appear in the workspace.
