Models are like "mini scenes" that can be easily reused in scenes and projects. In fact, exporting and importing models is how you can copy and share objects and object hierarchies between scenes.
You can import a Softimage model (File 
Import Model) for reuse in any scene. When you import the model it is saved internally to the scene file.
You can also import a model as a referenced model (File Import Referenced Model), so that any changes made to the model will be reflected in your scene the next time you open the scene or update the reference.
For details about importing models and working with models in general, see Models.
You can export models created in Softimage for use in other scenes. When you export a model, a copy is saved as an independent file. The exported model contains only its internal relationships — the export process removes constraints, modeling relationships, expressions, linked parameters, and so on if they involve elements that are not children of the model. The file names of exported models have an .emdl extension and are saved to the Models folder of the project.
For details about exporting models, see Exporting Models.
