In drafting, the two most important things are precision and speed.

You want to finish your drawing as fast as possible, but you don't want to undermine your drawing's precision.

It is best to learn precision before speed because it is easier to learn to speed up the creation process than it is to improve accuracy. In this chapter we will tackle many commands, but drafting with precision is most important.

The Line command is used to draw segments of straight lines.

There are many methods available to draw precise shapes using the Line command (which we will learn later), but for now, we will type the coordinates in the Command Window.

On the Ribbon, make sure you are at the Home tab. Using the Draw panel, click the Line button.

The following prompts will appear:
