Hello good people of shapeways . I have just finished a sculpture of Mozart, but I messed around while trying to decimate the torso (see attached), now it only has a partial back side, I can't seem to do anything with it, I need the top to be solid and fit onto the head as a key (see file in next message 'headfix') and be ready for printing (I have pre-sculpted details (buttons, scarf, embroidery, that will be added also) but first I need the piece to be solid. before I can do anything. Please help!!!!!!!!!!!
