When you import a service provider, you also import its service interfaces. However, you can manually create a service interface as follows:
Open the Interfaces tab in the property sheet of a service provider, and click the Add a Row tool (see Service provider property sheet Service Interfaces tab)
Right-click the service provider in the Browser, and select
The list of service interfaces accessible from the Model menu only allows you to visualize all service interfaces for all service providers within the model. You cannot create service interfaces from this list.
