SAMS3D - no, you can only export an object that was originally in another format and imported into Bryce, and as far as I know, you have to export it in the same format it was imported in - I've heard that Bryce crashes if you try to use it to convert to a different format. So - if you import a *.3Ds object, you can later export it as a *.3Ds, but not as an *.obj. And you can't export anything originally created in Bryce except a terrain or lattice.
