Ok, so forgive me but I'm not a CNC lathe guy, heck, I'm barely a CNC mill guy

but I will be attempting to put together a CNC lathe in the near future so I need a bit of info/help here if you don't mind?
I have no problems drawing up a dxf of a part for the mill, yet, I'm not sure how to start to draw a dxf for the lathe. Am I to just draw half the diameter/profile and then import that into my cam program?
I will be trying to use "LCam Turn" but I'm honestly not sure where to begin. It's funny, I've been a "manual" guy for over 20 years and when it comes to some of this design stuff, I'm a complete idiot lol!
Thanks for your help-
Dave
