Autodesk DirectConnect
            lets you import Autodesk InventorĀ® part (*.ipt) and assembly (*.iam)
            files into supported Autodesk software. 
         
         Exporting directly to
            Autodesk Inventor is not supported at the moment. You must use one
            of these formats: STEP, IGES, DWG, PTC Granite, UGS-NX.
         
         Software prerequisites
            
               - Install the Autodesk product where you
                  plan to import files using this format. (The Autodesk DirectConnect
                  software installs at the same time.) The software does not require
                  an Autodesk DirectConnect license to import this file format.
               
Type of data imported
            
            We import NURBS for this
               file format. The software maintains the following additional information
               on import: 
            
               - BREP Bodies
- Data organization
- Tolerances and units
- Material Colors and simple transparency
Limitations
               
                  - WorkSources, Display Meshes, and 2D/3D
                     Sketches get automatically excluded when importing an Autodesk InventorĀ®
                     file. Some cylindrical surfaces (pipes) do not trim properly.
