I've had friends who've tried other CAD (Computer Aided Design) software because AutoCAD was pricey. In the end, the full-features of AutoCAD aren't available in other CAD software. If you're needing a CAD software to just "do something", then google a cheap alternative. if you're needing a CAD software to work on a schemata to share with a CAD person, then it's best to get AutoCAD.
