do you have the free edition from a magazine or something if i remember right you cant import except dxf and 3dmf or whatever but if you have a file conversion program like 3d exploration you got it made just convert them to the dxf or whatever if you dont have 3d exploration you can get a almost full version from thier website that works for 30days get it and do some serious file conversions or just go out and buy bryce4 which is ten times better than bryce3 or better yet get 5 and you wont be sorry, except for the slow rendering and a few other litte things but try 3d exploration for now and start having some serious fun! cheers!
