I would promote the sales of CAD programs to contractors and the like, if an architect feels that this would lose him business then he isn't doing something right in the first place.
Working WITH contractors not against them makes better buildings, plain and simple. Imagine how much time it would save to be able to get the contractor to snap dimensions on the cad drawing instead of measuring off the prints!
Just because one is an architect does not mean they have a better design sense that the average human, I have built and worked for many architects that had no business designing houses or even plastic cups for that matter. Protectionism will only lead to hostility, arrogance and self proclaimed superiority will only be one's down fall.
I have worked for one of the greatest architects alive and the last thing he did was assume he knew more that me, I was 18 and a cabinetmaker, he was in his mid 50's and treated me like I was his teacher. That architect would be Frank Gehery.
I have worked with Peter Pfau, Frank Israel, Gehery, Mike Rotondi and a few more, non of which, besides Gehery had the ability to step down off the 'academic' high horse and listen to the DIYers.
Hey, if you sell to them you might learn something, Gehery did!
