The leading CAD program in the US is at Tyler School of Art in
Philadelphia, under the leadership of Stanley Lechtzin. Stanley has
been exploring the digital environment of more than 20 years and has
made it a central part of the program at Tyler. The facilities are
excellent and from what I could tell in my day there as a visiting
artist, there is a very high level of dialog on the subject.
While some other schools have brought CAD/CAM into their programs in
recent years, none in the US to my knowledge has done so with the
depth and commitment of Tyler.
I suggest you Google (I don’t have the address on this computer, try
Tyler School of Art, CAD/CAM) them and find their website. Each grad
student is required to do a website as part of their thesis, so
there is lots to see. You could also go to the SNAG site at
SNAGMetalsmith.org and look under schools. It’s an excellent
resource for all kinds if info.
Good luck with your hunt,
