To save a V21 TCW as a V18 TCW, select the "TurboCAD 18" line in "Save as type". The "Setup" dialog doesn't have anything special. You would want to add something to the drawing name to note that it's a V18 file; i.e. "drawing X (V18)". I don't think you'll lose anything, except possibly in a PartTree situation; such as a "Fillet Edges" entry. Objects that are ACIS Solid objects and any 2D objects should make the trip intact.
