Rhino 5.0 very solid software
I use Rhino almost every day and I'm very impressed with it. I had previously learned cad on another program, but Rhino is much more stream lined and versatile. I use the software in a cabinet shop and it gets used for cabinet design, blueprints, counter top design as well as any other design that needs precision and automation. Combined with Rhino's ability to be expanded via macros, scripts, and plug-ins, I believe that it is among the best software for your money that there is. I would definitely recommend it to anyone!
