   When Rhino opens a non-3dm model, the title bar reflects the name of the model that was opened. When the model is saved for the first time, this model name is entered as the file name.

To save as or export a Rhino model

1. On the File menu, click Export Selected or Save As.
2. In the dialog box, the Files of type list displays the currently supported file types for export.
3. In the Files of type box, select the supported file type.
4. In the File name box, select or type a file name.
5. Specify what is to be saved.

Options
Save small	Though clearing the render meshes makes the file smaller, it will shade and render more slowly the next time you open the file.
Save geometry only	Saves geometry objects only. No layers, materials, properties, notes, or units settings are saved. This is similar to exporting the objects. A new file is made, but it does not become your active Rhino model.
Save textures	Embeds external textures used by materials, environments and decals into the model.

6. If the export can be configured, click the Options button to specify export settings.
7. If the file type creates only mesh objects, in the Polygon Mesh Objects dialog box, specify the mesh settings.
