Hi, I am trying to use pdb files to generate surface models (using multiscale models) to convert to .obj files for use with Maya software. I keep getting the same error and can't decide if I'm just not using the command appropriately or if the is something else wrong with the files. Any ideas? Thanks, Cheri
