As you can imagine I see herds of various cad animals in my classes. In some instances the cages are open and the animals are of too many species to count. In other locations, the stripes might tend to the same color and pattern. All along there are those that get the state of the software, and evolve to use tools, to wear khakis and Polo's, and leave the world or red lines behind. In many ways the state of the product is such that a small properly trained and motivated team can do far more with fewer hands on mice. In some instances there will always be room for some intern level position with cad. However, as time goes by those low order operations will mostly be gone away.
Herein lies the kicker, the users must be trained, and they need a uniform introduction to the tools. It does little good if, one or two folks attack this thing head on. I once hired four guys at that were right out of some cad school, and three did quite well, and the other had no aptitude for civil. The reason behind hiring them was they would have no bad habits, and would know cad, the civil stuff we could teach them.
As I see it the smarter the hand pushing that mouse around the higher your profit margin.
