METHODS OF ENTERING COMMANDS

AutoCAD has 3 different methods of entering commands. All 3 methods will accomplish
the same end result. AutoCAD allows you to use the method you prefer. The following
are descriptions of all 3 methods and an example of how each one would be used to
start a command such as the Line command.

1. Pull down Menu (page 2-8) (Select Draw / Line)

a. Move the cursor to the Menu Bar
b. Click on a Menu header such as “Draw”
c. Slide the cursor down the list of commands and click to select.


2. Tool Bars (page 2-9) (Select the Line icon from the Draw toolbar)

Move the cursor to an icon on a toolbar and press the left mouse button.

3. Keyboard (Type L and <enter>)

Type the command on the command line.





What is a SHORTCUT menu?
In addition to the methods listed above, AutoCAD has shortcut menus. Shortcut Menus
give you quick access to command options. Shortcut Menus are only available when
brackets [ ] enclose the options, on the command line. (Example below)
To activate a Shortcut Menu, press the right mouse button.

Example:
Select: Draw / Circle / Center, Radius

_circle Specify center point for circle or [3P/2P/Ttr (tan tan radius)]:


If you press the right mouse
button now, the shortcut
menu on the left will appear.
This allows you to select the
options 3P, 2P or Ttr with
the mouse rather than
typing your selection.






Selecting the Shortcut menus is the AutoCAD’s “Heads Up” drawing method within
AutoCAD. “Heads Up” means always looking up at the screen and not down at the
keyboard. Using this method should improve your efficiency and productivity.

DRAWING LINES

A LINE can be one segment or a series of connected segments. Each segment is a
individual object.



One segment Series of connected segments


Start the Line command by using one of the following methods:

Type = L <enter>
PULLDOWN MENU = DRAW / LINE
TOOLBAR = DRAW



Lines are drawn by specifying the locations for the endpoints.
Move the cursor to the location of the “first” endpoint then press the left mouse button.
Move the cursor again to the “next” endpoint and press the left mouse button.
Continue locating “next” endpoints until you want to stop.

2. Next

5. Next

1. First

3. Next

There are 3 ways to Stop drawing a line: 1. Press <enter> key. 2. Press <Space Bar>
or 3. Press the right mouse button then select enter from the short cut menu.


To draw perfectly Horizontal or Vertical lines select the
ORTHO mode by clicking on the ORTHO button on the
Status Bar or pressing F8.



3. Type C <enter>

2. Second line
segment 1. First line segment


Once you have drawn two or more line segments, the endpoint of
the last line segment drawn can be connected automatically to the
first endpoint using the CLOSE option.

To use this option, draw two or more line segments,
then type C <enter>.
