Working with CAD doesn't have to break the bank.  Here are at least 4 Free alternatives to AutoCAD for working with CAD objects and drawings.

Check out QCAD

QCAD is THE application you should use if you’re looking to create technical drawings be it for surveys, buildings, mechanical parts or even schematics and diagrams. Since it is open source, QCAD’s focus is more towards modularity, extensibility and portability. Its 2D CAD platform is powerful but yet easy to use even for a beginner who has little to no experience in CAD applications.

Don't Forget Draftsight

DraftSight is a free 2D CAD editor that is good for professional CAD users, students and educator, especially if you need to create, edit and view your project in the native DWG file format. It comes with a nice set of features that allows you to generate professional looking plans using lines, polylines, dimensions, text and others. The interface is relatively dull, but this may appeal to those who prefer a minimalist and simple CAD software.
