Different portions of the drawing can be selected for export to a 3ds file.
To export a 3ds file:
If 3D objects from only one layer should be exported, make that layer active. If only selected objects should be exported, select the objects.
Select File > Export > Export 3DS (3D only).
The Export 3DS Options dialog box opens; the options available on the lower part of the dialog box depend on which group of items were selected for export.
Click to show/hide the parameters.
Select the types of objects to export, and then click OK.
Specify the export file name and destination, and then click Save.
