Eddy, I'm trying to sway towards packages that have a lathe option to try and avoid having different packages for everything.

Thanks John.
I set the profile depths to appear how I'd expect the finished article to look. Is that not the best way to do it?
The double entities are probably a result of me trying various options and not tidying up.

In all honesty, at the moment I'm struggling to see any benefit of Dolphin over CamBam, at least for the standard version, and they don't let you trial the Pro version. At least with CamBam, if I need to add anything to the drawing, I just need to add it in and not mess around switching between CAD and CAM.
