Bryce cannot read or import 3dmf files. I guess there are different file types under that standard. I'm downloading 3dexplorer from xdsoft, so we'll see if it works (thanks archlite). Polytrans and Design Workshop are the only other programs I know of that will export 3dmf files, and Polytrans is expensive. Keep in mind that 3dmf is a Mac file standard, and Windows does not do a good job handling it.
