Well at this point it's time to start drawing.
On the "draw" toolbar click the left mouse button on the command 'line'
is the key with this icon = LINE
Now look what came written in the "command line".
The program suggesting steps that have to do to create a line, in this case is asking you to "Specify first point" (to specify the first point of the line).
Now click with the mouse in a point mean any of the canvas and then looks back at what appears in the "command line":
"Specify next point" (specify the second point).
Now move the mouse on one side and you'll see that you are creating a line, before clicking the second test with the mouse to rotate around the first point you've already laid down, you'll see the line that follows your movement in all directions .
Click and then at another point in the drawing slightly away from the first, doing so will create the first line between the two points just defined.
At this point, the program gives you the opportunity to continue to create more connected line segments to the first, by clicking with the mouse in other areas of the screen.
To stop the command and end the line, click the right mouse button, or press the "enter" key on your keyboard.
You can resume the command line just completed by pressing one of two buttons (right-click or enter), or by clicking again the "line" button on the toolbar.
To create a line and then it took at least four clicks of the mouse:
beginning of the command, the first point, second point, the end of the control (Right).
To run the various commands of AutoCAD you must use different combinations of mouse buttons that we will see from time to time, with practice you will become automatic and runs them without thinking.
However, if during the execution of this or any other commands you seem to have some wrong step by clicking the "esc" key on your keyboard to quit the command and you can start over.
The latest versions of AutoCAD may be that during the execution of commands, some information and numbers will be displayed next to the cross-hairs, and repeat the "command line" informations, and others. It's called "dynamic input and can be turned off by clicking on the" DYN "bottom of the screen, under the command line. Personally I find it annoying but it is subjective, however, should turn it off initially.
The “ORTHO” function.
Now try to press the key "F8" on your keyboard and get the command line (line), click to establish the first point and then try to move the mouse back to it, you'll see that now the line no longer moves in all directions but only in the vertical and horizontal.
Click again to the second point of the line and then with the right to end the command.
Continue to press several times F8 and watch the "command line" and other small buttons below it.
Press "F8" then turn on or off the "ortho", or alternatively you can click on the button under the "command line".
This function key allows us to define with precision vertical and horizontal lines, but is also useful to move or copy items in a right angle with each other in technical design and therefore should be used whenever it can be activated or deactivated at any time, even during the execution of a command.
Drawing with AutoCAD you should not go to the event, although it seems to do so, should not be drawn without vertical or horizontal "ortho" activated.
