Lines, circles, and other elements of geometry make up the heart of your drawing. AutoCAD offers many different drawing commands, many ways to use them to draw objects precisely, and many properties for controlling the on-screen and plotted appearance of objects. After you draw your geometry, you'll probably spend at least as much time editing it as your design and drawings evolve. And in the process, you'll need to zoom in and out and pan all around to see how the entire drawing is coming together.

Drawing geometry, editing it, and changing the displayed view are the foundation of the drawing process; this part shows you how to make that foundation solid.
