William:
I have used Autocad for all my golf course construction drawings since 1992 and the biggest concern people have with CAD drawings is the way that the final product may look. Does it appear antiseptic, unnatural, etc.? The only impact CAD should have on design is in the efficiencies of production and not on the final product.
(A) If you are talented enough with CAD, you can create natural appearing and interesting lines.
(B) CAD does not do design at all, it is all about the input from the designer. There used to be this Intergraph product and the sales people would call me and talk about how this software would spit out a routing based on the topo and property line of a site. He thought it was the future of design. I doubt there has ever been a golf course built with an Intergraph routing, or at least I hope not.
(C) Lastly, if anything gets to the field with a "computer look", then hopefully the Architect and shapers will make field adjustments.
I think CAD has had a positive influence on design in its ability to allow more efficiency during production, but never on the actual design of a golf course directly.
