Not really. You can save as a STEP (dumb solid) or other 3D format. There is a plug-in that uses the ATB to send files back and forth, but it is not a no-brainer to install. It allows 3.0 files to be opened in 2.0. You can't modify the model in 2.0, but you can add features that can be 'grafted' onto the model when re-opened in 3.0. Check TPI 132326 for details. Regards
