So CAM technology is being developed to work with popular entry level CAD technology. That's what you get when software development is driven primarily by marketing desires. Nothing ground breaking here, same old same old.
Machining modules written to run in Autocad and Cadkey, for example, have been available for eons. Again, old ideas, different software.
Nothing is ground breaking with this "new" CAM technology either, its simply already existing technology dressed up in a new wardrobe. However, in most cases the wardrobe is incomplete.
