A quick check on Wikipedia shows that this $1600 to $3100 program for Mac OSX, imports the following:


DWG, DXF, PDF, EPSF, 3DS, IGES, SAT, Parasolid X_T, Sketchup, IFC, SHP, JPEG, BMP, PNG, PSD, SGI, TIFF, TGA

(Moi shows export types of IGES, SAT, 3DS, Skp, so it looks like there are 4 possibilities...?)
