you looked at a pre-existing sample drawing. This time you will begin to draw on your own drawing, by creating door that will he used in later exercises. First, though, you must learn how to the AutoCAD what you want and even more important, to understand what AutoCAD wants from you.

To begin a drawing, follow these steps:
1. Click the Line tool on the Draw toolbar, or type L.J, You’ve just issued the Line command. AutoCAD responds in two ways, First you see the message.
Specify first point:
in the command prompt, asking you to select a point to begin your line. Also, the cursor has changed its appearance; it no longer has a square in the cross hairs. This is a clue telling you to pick a point to start a line.
2. Using the left mouse button, select a point on the screen near the center. As you select the Point, AutoCAD changes the prompt to
Specify next Point or [Undo]:
Now as you move the mouse around, notice a line with one end fixed on the point you just see and the other end following the cursor.
If you move the cursor to a location directly to the left or right of the point you clicked on, you’ll see a dotted horizontal line appear, along with a tool tip-like message that appears at the cursor. This action also occurs when pointing directly up or down. In fact, Your cursor will seem to jump to a horizontal or vertical position.
This is a feature called Polar Tracking. It helps to restrict your line to an exact horizontal or vertical direction like a square and triangle. It can be turned on or of by clicking the Polar button in the status bar. If you don’t see it, chances are it’s just been turned off. You’ll learn more about Polar Tracking.
Now continue with the Line command:
3. Move the cursor to a point below and to the right of the first point you selected, and press he left mouse button again. The first rubber-banding line is now fixed between the two points you selected, and a second rubber-banding line appears.
4. If the line you drew isn’t the exact length you Want you can back up during the Line command and change it. To do this, click Undo in the Standard toolbar, or type U.J from the keyboard. Now the line you drew previously will rubber-band as if you hadn’t selected the second point to fix its length.
You’ve just drawn, and then un drawn; a line of an arbitrary length. The Line command is still active. There are two things that tell you that you are in the middle of a command, as mentioned above. If you don’t see the word Command in the bottom of the Command window, You know a command is still active. Also, the cursor will be the plain cross hair without the little box at it’s intersection.
