Adding custom parts to SolidWorks Routing Libraries

I am seeking help in adding components to be used within the SolidWorks routing library.  I have successfully created some components like PVC reducers and flanges.  But I am stuck on the adding my Tees and a custom pipe.  each of these being configuration files.  If anyone has a good teaching tutorial to help me understand the following items for the RTEE components, I would be very grateful.
