You are using what is called the "Designer Flow".
In this flow, all of the 3D Model Mappings are saved within the design project. There is currently no method in this flow to save the mappings to a Central location so they can be used between other designs, and the mappings must be done on a per design basis.
In the Enterprise Flow, xDM Library tools formerly know as DMS allow you to save the Model Mappings to the Central library. Contact your Mentor AE to provide more information on this flow and method, or you can view the link below for more information.
