INTRODUCTION AUTOCAD 2D
● AutoCAD allows the designer to use and manage it on multiple machines using network licensing. Being an easily
available program, AutoCAD is used globally by students, teachers, architects, freelancers, engineers, fashion
designers. Like other CAD programs, AutoCAD also works on a database of geometric systems including points, lines,
arcs, etc. The user works on the application through the commands, editing or drawing is done from the inbuilt
command line. AutoCAD is issued free of cost to students, educators, and institutions
● AutoCAD is globally used by surveyors, designers, engineers, drafters. Globally, AutoCAD has proven as an efficient
and user-friendly program. Commercial drafting and computer-aided design(CAD) software applications are AutoCAD.
AutoCAD software is recognized internationally for its remarkable editing capabilities, which make it likely to digitally
draw building plans or recreate 3D images. This software was developed in the year 1982 by Autodesk.
1. DRAWING COMMANDS
● This is the list of some of the most basic AutoCAD commands which every
AutoCAD user should know
● SHORTCUT/ COMMAND DESCRIPTION
● A/ ARC Create an arc
● AR/ ARRAY Make a rectangle, polar or path array
● B/ BLOCK Create a block
● BCOUNT Count the number of blocks in your drawing
● C/ CIRCLE Create a circle
● GROUP Group multiple objects into a single unit
● L/ LINE Create a simple line
● MI/ MIRROR Produce a mirror copy of an object
● MI/ MIRROR Produce a mirror copy of an object
● MLINE Create multiple parallel lines
● PO/ POINT Create a single point within a drawing
2. MODIFIED COMMANDS
SHORTCUT/ COMMAND DESCRIPTION
● BASE Alter the base point of a drawing without changing its origin
● BREAK Create a break (or gaps) in objects at one or two points
● BURST Explode a block but retain its attribute settings and layer definition
● CHA/ CHAMFER Add slanted edges to sharp corners of objects
● COPYBASE Copy an object according to a base point
● DIVIDE Divide objects into multiple equal parts
● F/ FILLET Add rounded corners to the sharp edges of objects
● LA/ LAYERS Open the Layer Properties Manage Palette
● PURGE Remove unused objects from a drawing
● SC/ SCALE Change the scale of an object
● SCALETEXT Change the scale of text
● TR/ TRIM Trim a shape or line
● UNITS Alter the unit settings of your drawing
● X/ EXPLODE Break up an object into its individual components—i.e., a polyline into simple
lines
3. ATTRIBUTES
● Click Home tabBlock panelDefine Attributes. Find
● In the Attribute Definition dialog box, set the attribute modes and enter tag information, location,
and text options.
● Click OK.
● Create or redefine a block (BLOCK). When you are prompted to select objects for the block,
include the attribute in the selection set.
● These commands and system variables are used to work with block attributes.
● Commands
● ATTDEF (Command)
● ATTDISP (Command)
● ATTEDIT (Command)
● ATTEXT (Command)
● ATTIPEDIT (Command)
● ATTREDEF (Command)
4. AUTOCAD PROPERTIES COMMANDS
● The Properties Palette
● The Properties palette is an essential tool. You can open it with the PROPERTIES command
(enter PR in the Command window), you can press Ctrl + 1, or you can click the tiny arrow in the
Properties panel on the Home tab—whichever you prefer.
PROPERTIES COMMANDS
Match the Properties of Objects
● For a fast way to copy the properties of a selected object to other objects, use the Match
Properties tool, or enter MATCHPROP or MA in the Command window.
1. After you click the Match Propetries tool, select the source object, and then select all of the objects
that you want to modify.
2. Linetypes
3. Dashed and other non-continuous linetypes are assigned from the Properties panel. You first need
to load a linetype before you can assign it.
4. In the Linetype drop-down list, click Other
5. This action displays the Linetype manager
dialog box
● Lineweights
The Lineweight property provides a way to display different thicknesses for selected objects. The.
thickness of the lines remain constant regardless of the scale of the view. In a layout, lineweights are always
displayed and printed in real-world units.
Lineweights can also be assigned from the Properties panel.
5. AUTOCAD BLOCKS
● Insert a Block
Typically, each of these blocks is an individual drawing file, perhaps saved in a folder with
similar. drawing files. When you need to insert one into your current drawing file, you use the
INSERT command
The first time you insert the drawing as a block, you need to click Browse to locate the
● drawing file. Make sure you organize your blocks into easy-to-find folders.
Once inserted, the block definition is stored in your current drawing. From then on, you can choose
e Name drop-down list without needing to click the Browse
Create a Block Definition
● Instead of creating a drawing file to be inserted as a block, you might want to create a block definition
directly in your current drawing. Use this method if you do not plan to insert the block into any other
drawing. In that case, use the BLOCK command to create the block definition.
● For example, this is how you could create a module for a cubicle design.
Create the objects for the block.
● Start the BLOCK command.
● Enter a name for the block, in this case Quad-Cube.
● Select the objects that you created for the block (click 1 and 2).
● Specify the block insertion point.
