AUTOCADSTARTING OF AUTOCAD:-
To start AutoCAD, double click application icon on the windows desktop. If desktop icon is not created, pick Start → Programs→AutoCAD.
Under standing Menu System:-When we start AutoCAD, We will see AutoCAD windows screen.
The screen contain various components let us discuss these components & their significance. The main AutoCAD window screen can be tested as follows.
1. Pull Down Menu Bar.
2. Screen Menu.
3. Status line.
4. Drawing Area.
5. Curser.
6. Tool Bar.
7. Yes Icon.
Menu Bar:-The Menu Bar appears on the top of the AutoCAD screen. It
contains various commands in different categories &the pull down menu. Some of the pull down contains child menus represents sub commands.
Screen Menu:-The Screen menu appears on the right side of the drawing window,
which represents a set of commands. A command in this menu may contain the set of sub commands. The command in this menu contains a set of sub commands, which appears on the sub menu. When that command is selected the screen contains full AutoCAD command set where as menu bar contains only that used commands when we select it in a screen menu another sub menu may appear which give sub commands. Click AutoCAD on the top of the screen menu to come to the
AutoCAD 2000 1

main menu of the screen menu. Click**** to get cursor menu [also called assist menu or tools menu].
The Status Line:-The status line displays the X&Y co-ordinates of the current cursor
position & also the button representing ON/OFF status of modes such as grid, ortho, these buttons out of toggle switches [we can double click on it to make its status ON/OFF]
Tool Bars:- It contains many icons of particular category to access a
command directly without using menu system. The toolbars consume a lot of space on the screen, which in turns limits drawing area. So they can be normally kept of f (use view→ toolbars).
Cursor Menu:-Curser menu appears on graphic window when mid button of
mouse (Or shift+ right mouse button) is pressed. The options under cursor menu are used to locate exact points like center, end point of objects. This helps to produce accurate drawings.
Yes Icon:-AutoCAD uses a fixed Cartesian coordinate system called Word
Co-ordinate System which shows the X, Y&Z direction in space of the drawing .But this system can be represented according user requirement. Then it is called as User Co-ordinate System (UCS).The UCS is represented by a UCS icon (Arrow in X And Y Direction) on the left corner of the screen. The letter W appearing in the UCS icon indicates the World Co-ordinate System(WCS).

Dialog Box:-When some commands like point, style, insert, colour are selected
dialog box will appear. An image file displays a small representation of how a feature will appear in the drawing.
Command Prompt Area:-In this area commands can be entered using keyboard. Information
of sub commands & error messages are also displayed in this area.
Cursor (Cross Hair):-It is the thin cross line which moves respect to the movement of the
mouse. It locates the selection point.
Pick Box:-It is the small box of the center of the cursor or in some cases
without the cursor, which is used to select the object.
Limits:-Drawing limits is the invisible boundary to get the drawing. It
should be large enough to contain the drawing & other related parts of it.Commands: Limits press enter.Menu: FormatDrawing limits.ON/Off/<lower left corner><0, 0><: (0,) enter lower co-ordinate value & press enter.Upper right corner <12, 9> (30,200) enter the co-ordinate value enter.
Grid & Snap:-Grid:-
It is pattern of dots at a specified spacing that extends over the area specified by the limits. The grid gives a visual display on the screen of the distance between points. Using grid it is possible to directly pick

DEPARTMENT OF ELECTRICAL & ELECTRONICS
points on the screen at specific distance. These dots will not appear on print out of drawings.Command: GRID enter. Grid spacing (X) ON/OFF/SNAP/ASPECT<.5>: enter value (say 10) enter.
Snap:-The grid gives a visual display of positions on screen but is it is not
possible to pick exact position by eye judgment .So an option is given to set snap distance when snap is set , cursor movement is restricted. That is the cursor will move only in steps of snap distance. If snap is made off, the cursor movement will be smooth.Command: SNAP enter.ON/OFF/Aspect/rotate/style<0.5>: enter value (say B) enter.Grid, Snap, & other settings can be done by using the dialog box, which is occessed by menu.Menu: ToolsDrafting settings..Command: DORMODES enter.Enter X&Y spacing for grid & snap & click ok.
