Selecting AutoCAD CommandsSelecting AutoCAD Commands Commands may be selected in four
ways 1. Executed by picking a toolbar button or
icon
2. Selected from one of the pull-down menus
3. Selected from the digitizer table menu overlay
4. Typed at the keyboard

Selecting AutoCAD CommandsSelecting AutoCAD Commands Command Line Editing
You can select previously used commands by using the up and down arrow keys
This capability allows for fast, repeated use of the same command. Just hit the “up” arrow to recall the
command.

The [Enter] key and the [Spacebar]The [Enter] key and the [Spacebar] The [Spacebar] functions (most of
the time) like the [Enter] key.
A good habit is to use your left thumb as the [Enter] key.

Drawing AidsDrawing Aids AutoCAD provides drawing aids that
help prepare the drawing layout, increase speed and efficiency and ensure accuracy. GRID SNAP ORTHO
Function Keys, Grid, Snap, Limits 17
The GRIDThe GRID A grid is a predefined spacing of points
which is used to help lay out a drawing
The GRID command places this pattern of dots at any desired spacing. It can be equal or non-equal spacing The grid pattern shows only within the
drawing limits Entering the GRID command provides a
prompt showing the default grid spacing and several other options.
The GRIDThe GRID GRID
Is a COMMAND and a TOGGLE
Command Displays a grid pattern in the current
viewport.
Toggle Turns the display of the grid pattern in the
current viewport ON or OFF.

Function Keys, Grid, Snap, Limits 22
GRID CommandGRID Command GRID can also be set by using the
Command: prompt. More tedious to use than right-clicking GRID on
Status Bar. Command: GRID Grid spacing (X) or ON/OFF/Snap/Aspect
<0.5…): 0.25
Function Keys, Grid, Snap, Limits 23
GRID CommandGRID Command GRID on or off:
Click the GRID button on the Status Bar or
The [F7] function key or
[Ctrl + [G]
Function Keys, Grid, Snap, Limits 24
GRID Command – Aspect OptionGRID Command – Aspect Option Aspect Option
Setting a different horizontal/vertical grid spacing can be done.
Type a different X, Y value.
From the Command: prompt Select the Aspect option of the GRID
command.
Function Keys, Grid, Snap, Limits 26
GRID Command – Aspect OptionGRID Command – Aspect Option Command: GRID Grid spacing (X) or
ON/OFF/Snap/Aspect<current>: A Horizontal spacing (X) <0.5000>: 1 Vertical spacing (Y) <0.5000>: .5
The SNAPThe SNAP SNAP
Is a COMMAND and a TOGGLE
Command Restricts cursor movement to specified
intervals.
Toggle Turns the SNAP action ON or OFF.

Function Keys, Grid, Snap, Limits 29
SNAPSNAP The cursor crosshairs move freely on
the screen It may be difficult to accurately place a
point It would be desirable to cause the
cursor to move only to an invisible grid.
This is called “SNAP”. Very useful Makes drawing much easier and more
accurate
Function Keys, Grid, Snap, Limits 30
SNAPSNAP Snap grid or snap resolution
controls the movement of the cross-hairs to this invisible grid.
It can be set to a different value than the GRID command.
The two commands SNAP and GRID are generally used together.
Function Keys, Grid, Snap, Limits 32
The SNAP CommandThe SNAP Command Properly setting the Snap Grid can
greatly increase your drawing speed.
The SNAP command is used to set the invisible snap grid.
SNAP SettingsRight-click SNAP button
Function Keys, Grid, Snap, Limits 34
The SNAP CommandThe SNAP Command Setting SNAP can also be done at the
Command: prompt Command: SNAP Snap spacing or
ON/OFF/Aspect/Rotate/Style <current>
Pressing [Enter] accepts the value shown in brackets. If a different spacing is required, such as
0.25, enter the new value.
Function Keys, Grid, Snap, Limits 35
The SNAP CommandThe SNAP Command Command: SNAP
Snap spacing or ON/OFF/Aspect/Rotate/Style <current>: 0.25
This sets up snap at 0.25
Function Keys, Grid, Snap, Limits 37
Rotating the SNAP GridRotating the SNAP Grid The normal snap grid is horizontal
rows and vertical columns.
The grid can be rotated using the Rotate option of the SNAP command.
Command: SNAPSnap spacing or ON/OFF/Aspect/Rotate/Style
<current>: RBasepoint <0.0000,0.000>:(press [Enter], type a
new coordinate value, or pick a new base point.Rotation angle <0>: 25
Function Keys, Grid, Snap, Limits 38
Setting the SNAP StyleSetting the SNAP Style The Style option of the SNAP
command allows you to set the snap grid to either a Standard (default) or Isometric pattern.
Command: SNAP Snap spacing or
ON/OFF/Aspect/Rotate/Style <current>: S Standard/Isometric <current> S
Function Keys, Grid, Snap, Limits 39
Setting Grid Spacing Relative To SNAP SpacingSetting Grid Spacing Relative To SNAP Spacing
The visible grid can be set to be the same as the invisible snap grid.
Choose the Snap option of the GRID command.
Function Keys, Grid, Snap, Limits 40
Setting Grid Spacing Relative To SNAP SpacingSetting Grid Spacing Relative To SNAP Spacing
Command: GRID Grid spacing or ON/OFF/Aspect
<current>: 2x
In this case the GRID spacing would be 2x the SNAP setting.

The AutoCAD Drawing Area The AutoCAD Drawing Area The AutoCAD drawing area is
basically INFINITE in all directions.
Think “outer space”
It is beneficial to “define a drawing area” that represents the size of your project.
LIMITS are the extent of the drawing area.
Function Keys, Grid, Snap, Limits 43
The AutoCAD Drawing Area The AutoCAD Drawing Area LIMITS allow you to define a
reasonable drawing area.
This area can be turned On Off
You can draw outside the area when LIMITS is turned off.
Function Keys, Grid, Snap, Limits 44
LimitsLimits LIMITS are the extent of the drawing
area.
If you wanted a 17” x 11” drawing area, you would set the LIMITS to 17, 11. The first number is the horizontal
dimension. The second number is the vertical
dimension.
Function Keys, Grid, Snap, Limits 45
LimitsLimits LIMITS can be turned ON or OFF.
To set LIMITS, enter "LIMITS" at the Command: prompt.
AutoCAD restricts you from drawing outside the area defined by the LIMITS when the LIMTS are ON
Function Keys, Grid, Snap, Limits 46
LimitsLimits If you wanted an 11” x 8.5” drawing
area, you would set the LIMITS to 11, 8.5. The first number is the horizontal
dimension (X dimension) The second number is the vertical
dimension (Y dimension)
Function Keys, Grid, Snap, Limits 48
The ORTHO ModeThe ORTHO Mode The term ORTHO comes from the
word “orthogonal”, which means at “at right angles”.
The ORTHO mode restricts the cursor movement to the X, Y plane ONLY.
