This document provides information on various commands in AutoCAD, including how to fix the X and Y axes, use splines to create smooth curves, manage layers and properties, create geometric shapes like circles and polygons, trim and offset lines, use arrays to duplicate objects, and undo previous commands. Key commands covered are UCSICON, SPLINE, LAYER, DONUT, FILLET, XL, RAY, ELLIPSE, RECTANGLE, CIRCLE, POLYGON, TRIM, OFFSET, ARRAY, OOPS, POLYLINE, SKETCH, MLINE, EXTEND, EXPLODE, OSNAP, COPY, STRETCH, and UNDO.

SPLINE :
THIS COMMAND IS USE FOR
SMOOTH CURVE
SMOOTH CURVE
POLYLINE

3. LAYER : Name - Displays the layer name.
On - Controls if the layer is on or off. Select
the light bulb to turn the layer off on the
drawing.
Freeze in all VP - Pressing this will freeze
the layer in all viewports as well as the
current model view (see lesson 10 to
learn about viewports)
Lock - This handy feature locks a layer
preventing any content of the layer from
being modified.
Colour - Change this to whichever colour
you like. All objects drawn on the layer
will display the chosen colour provided
that the objects colour setting in the
object properties toolbar (shown above)
is set to 'By Layer'.
Linetype - Set the default linetype for all
objects drawn on the layer. i.e
continuous, dashed, dotted etc.
Lineweight - Set the thickness a line
appears .Default is no thickness. This
option can be toggled on/off on the
display by the LWT button above the
command console.
Plot - Select if the layer will be shown when
the drawing is plotted (printed).
The current layer, layer colour, linetype and
lineweight can all be controlled outside
of the layer properties manager via the
object properties toolbar.

DONUT :
COMMAND : DONUT
• SPECIFY INNER DIAMETER
• SPECYFY OUTER DIA METER
DONUT
FILLET :
COMMAND : F
• ERASE EXTRA LINES , WHEN LINES
ARE INTERSECTED

5. AUTO CAD V B ARCH
INFINITE LINE XL( CONSTRUCTION LINE) :
COMMAND : XL
• BY USING THIS COMMAND WE
GET INFINITE LINE LINES
HORIZONTALLY , VERTICALLY
AND AT VARIOUS ANGLES
HORIZONTAL LINE
VERTICAL LINE
LINE AT AN
ANGLE OF 45
DEGREE
RAY : COMMAND : RAY
• IT PROVIGES SEMI INFINITE
LINE
SEMI INFINITE LINE

6. AUTO CAD V B ARCH
ELLIPSE :
COMMAND : ELLIPSE
• WITH THIS COMAND WE CAN
GET A DESIRED ELLIPSE .
RECTANGLE : COMMAND : REC
• WITH THIS COMAND WE CAN
GET A DESIRED RECTANGLE.

7. AUTO CAD V B ARCH
CIRCLE :
COMMAND : C
• WITH THIS COMAND WE CAN
GET A DESIRED CIRCLE .
POLYGON
: COMMAND : POL
• WITH THIS COMAND WE CAN
GET A DESIRED POLYGON .
• FIRST YOU NEED TO GIVE NO.
OF SIDE .
• THEN CENTRE POINT OF
POLYGON

8. AUTO CAD V B ARCH
TRIM :
COMMAND - TR
• THE TRIM COMMAND IS AN
EXTREMELY USEFUL TOOL WHICH
WILL ERASE ALL PARTS OF AN
OBJECT BEYOND OR WITHIN ITS
INTERSECTION WITH ANOTHER
OBJECT
THIS LINE WILL GET
TRIMED
SELECTED LINE
OFFSET : COMMAND - O
• IT DULICATES LINE AT
REQUIRED DISTANCE
• FOR MULTIPLE OFFSET
WHEN REQUIRED LINE IS
SELCETED TYPE M ,
MULTIPLE LINES WILL
POSITIONED AT VARIOUS
FIXED DISTANCE

9. AUTO CAD V B ARCH
ARRAY :
• COMMAND : AR
• THE ARRAY COMMAND QUICKLY
CREATES COPIES OF A SELECTED
OBJECT(S) TO A SPECIFIED
SPACING
OOPS :
• COMMAND - OOPS
• RESTORES OBJECTS ERASED BY THE LAST ERASE COMMAND.
POLYLINE :
• COMMAND - PLINE
• A POLYLINE IS A CONNECTED SEQUENCE OF LINE OR ARC SEGMENTS
CREATED AS A SINGLE OBJECT. A RECTANGLE IS AN EXAMPLE OF A
POLYLINE.

COMMAND SKETCH
• RESULT CREATES A SERIES OF
FREEHAND LINE SEGMENTS
NOTES
•DRAWING WITH THE SKETCH
COMMAND CONTROLS A SCREEN-
BASED PEN WITH A POINTING DEVICE.
•SKETCH IS USEFUL FOR ENTERING
MAP OUTLINES, SIGNATURES, OR
OTHER FREEHAND DRAWINGS
SKETCH:
MLINE:
COMMAND : MLINE
• CONTINUE PARALLEL LINES
• BY USING SC COMMAND WE
CAN MANAGE DISTANCE
BETWEEN TWO PARALLEL LINES

11. AUTO CAD V B ARCH
• COMMAND : EX
• THE EXTEND COMMAND IS SIMILAR TO THE TRIM COMMAND IN HOW IT
FUNCTIONS, EXCEPT IT EXTENDS A SELECTED LINE TO A POINT OF
INTERSECTION OF ANOTHER SELECTED OBJECT.
EXTEND:
• THE EXPLODE COMMAND IS VERY STRAIGHT FORWARD. IT SIMPLY
BREAKS DOWN AN OBJECT DOWN TO ITS BASIC LINE ENTITIES.
EXPLODE:
• COMMAND : X
• THE OBJECT SNAPS (OSNAPS FOR SHORT) ARE DRAWING AIDS WHICH ARE
USED IN CONJUNCTION WITH OTHER COMMANDS TO HELP YOU DRAW
ACCURATELY.
OBJECT SNAP:
• COMMAND : OSNAP
COPY:
• COMMAND : CO

INCREASE SPACE IN BETWEEN VARIOUS
DRAWINGS.
UNDO :
• COMMAND : U
TO UNDO PREVIOUS COMANDS ,
THIS COMMAND IS GIVEN
