The normal lathe uses straight lines to connect the "dots". If a curve could be
used then the polyline object from autocad (or TurboCAD which I also use) could
be easily translated. The other lathe types are not really condusive to the
objects I use. I have attached a sample image of what I show to customers and
P&D for their use.
