tothemaking,

I would suggest you go to the Autodesk site and download the drawing viewer which ill provide for converting
from different versions of AutoCAD to earlier versions. Also save the drawing as version 12 dxf  for use by other programs such as Cambam.

Also be carefull how you create the drawing since you need to allow for the size tool you will be using. I use arc's as that will minimize the size of the drawing and not have a zillion points to deal with.
