Hi, I'm Rob!
I'm a (kinda) retired mechanical engineer. I've used many CAD programs in my career, most recently CATIA for designing tools to help put airplanes together. Now that I'm (mostly) a woodworker, SketchUp Pro gives me a lot of the same capabilities to design projects for my own workshop.
I've used SketchUp to assist in the design of the house we have now built in the middle of a cornfield, and to design many custom furniture projects. I paid the leap to Pro about a year ago, and I'm still climbing the LayOut learning curve.
I haven't had any formal SketchUp training (e.g. 3DBasecamp, etc.) but a lot of the CAD skills I developed I my career have been transferable to SketchUp. I'd rank myself as an intermediate user.
I've always wanted to build my own CNC router, and I've finally gotten started, using the C-Beam Machine XL mechanical bundle from OpenBuilds. It's awesome that OpenBuilds has the completed machine modeled in SketchUp and uploaded to the 3D Warehouse.
Well, you asked me the time, and I told you how to build a clock. Speaking of, it's time for me to ask my first question of the SketchUp Community. See you in the Forums!
All the best,
