Certainly not here!
Pretty much everyone who is serious about CADCAM has migrated to LinkedIn. There are very good reasons why this has happened!
Consider that it's much better to learn from those actually using CADCAM on a daily basis, and who have decades of hands on CADCAM experience, rather than from clueless idiots who can't talk about the needed specifics of CADCAM.
Clueless CADCAM idiots do things like post about CADCAM because they get a spam e-mail. They think that sharing spam e-mail, on a CADCAM program that they have never used, is doing someone a service. In the particular case I'm referring to, it's not even a 3D CAD program and it has a very bad reputation with many of its former users. What this clueless loser continues to post is noise and uninformed misinformation.
CADCAM Technology Leaders group on LinkedIn passed 1,400 members this week and will probably hit 3,000 members this year. It's easily the best place to discuss CADCAM on the Internet. Its membership reads like a who's who of the CADCAM industry... for damn good reason. The primary reason is that I started it and I run it.
