While it is true that the US is the land of milk and honey, I'm more of a vineyards and safari kind of guy.
I am an engineer and hold a few certifications in Solidworks for design, etc. I agree, CAD knowledge can come in very handy for home projects. My last offroading one was a custom winch-mount bumper and rock rails I built for my wife's JK Jeep Wrangler. I slapped together a few 2D drawings in AutoCAD for the sheetmetal, output to .DXF with toolpath and cut on a CNC plasma cutting machine. The rest of the tubing I bent with a machine bender intended for rigid electrical conduit. I wanted to go much further with the modifications, but she decided that she didn't want to get nearly as aggressive with things as what I had envisioned. Story of my life...
