The EAA + Solidworks program is a great way to get access to a professional level tool.
An alternative that I also recommend that is free for users that have a limited number designs in process at any one time is Onshape.

Good tutorials. It runs on the Onshape servers using your web browser and internet connection as the interface so it can run on any platform and does not require any software installation on your computer. It opens and generates all of the industry standard file formats so you can share files, use industry supplied models, and send files to machine shops and 3D printing shops.
Not immediately related to the thread but may allow others to start as similar project that otherwise do not have access to the design tools.
