||Maybe it all comes down to preference. It seems that as time goes on, more and more people have a rudimentary GIS skillset and less have any training in using AutoCAD.
I rarely meet entry level applicants or employees that have any Cad experience. Conversly, nearly all fresh out of collage or trade school people (that I interact with) have taken at least one GIS course. This may be more a function of the fact I work in the Earth Sciences...
My real point in the question is what, if any, are the technical software advantages of digitizing in CAD vs GIS?
