Hello, I'm Rob, Live in SW Michigan. I used Design CAD for years, under Microsoft Windows. A few years ago, I wised up, dumped everything "Microsoft", moved on to Linux Ubuntu, never looked back. In the process, I had to let Design CAD go as there is not a Linux version. I currently run Ubuntu 14.04.1 LTS. I'm also a Ham Radio operator, with an Extra Class - N8JUQ.
