You might want to try SketchUp, http://www.sketchup.com now acquired by Google. They have a free version as well as a paid version. For 3D, work, handily the easiest program I've used. And you got the usual suspects in TurboCAD http://www.turbocad.com. I started with TurboCAD many years ago but pretty much turn to SketchUp more these days. Most of my drawings are not particularly sophisticated.

Good luck.
