I'm a member of the local model engineering society (South Devon) and amongst 40-50 members, I seem to be the only one with a CNC interest. I know of one other member who is trying to get to grips with 3D CAD, but this seems very much a minority interest in the hobby/home machining community. I suspect that Fusion360 and OnShape, free for home users, might well change this over the next year or two although in my experience many model engineering types are not that quick to pick up new technology. Don't know about woodworkers - not an area that I'm part of. So, the chances of stumbling over someone who shares what seems to be very minority interests are pretty low! That's why, I suspect, this forum is a great chance to exchange ideas with others who actually understand what we're talking about.
