We are a digital printing company and have a job cover a tapered cylinder with graphics.  The shape is basically a cone with the top chopped off.  
I am trying to draw the cone in a cad program and then flatten or render it as a 2d object which should give me the curves and angle and shape to print my graphics in.

I have access to Autocad 2006 or TurboCad.
I am a cad newbie, but have been able to draw the objects in 3d. I just don't know the procedure or command to convert it to a 2d shape.

This link talks a bit about how to do it mathematically, but even they can't seem to agree on the correct formula.

Any ideas?

thanks for the points, the concentric ones are really the easiest. that program looks pretty sweet, and probably cost effective in a production setting. but it sure is alot more fun to draw em out! ;)
I'm probably going to make that file a pdf instead of a pic, should have to begin with. and find a diffrent place to host it.

Thanks again.
