Computer aided drafting software main window and its components

■ Model Space 

Created Drawing = a Model

Scale of the drawing = Full


   Paper Space

Plot


■ Workspaces : Workspace is a set of 

(1) Menu

(2) Toolbars

(3) Dockable windows in Drawing Area

(4) Command prompt : The line/s at the bottom of screen where one can see the 'command' is called the "Command Prompt".

When one type a command, one will see that command at Command Prompt / Command Line. CAD software uses this space to 'prompt' user for information. It will give one a lot of info and tell user where user is in the command. User requires to watch Command Line while learning CAD software.


■ 2D Drafting Workspace

(1) Quick access toolbar : Displays common buttons like New, Open, and Save.

New : Create new file.

Open : Open an existing drawing file.

Save : Saving the file.

(2) Ribbon

Tools

(3) WCS icon : WCS icon is the icon in the lower left corner of the CAD software's graphics area.

WCS stands for World Coordinate System icon that shows X and Y directions. X increases in the right direction and Y is increasing in the top.


(4) command prompt 

OR

(4) dynamic input display 

User communicates with CAD software on computer machine at command prompt or dynamic input display. 

CAD software may prompt the user at user interface, that is, command window or through dynamic input display.

(5) Status bar

Status bar accommodates following buttons, namely, 'SNAP, GRID, ORTHO etc......'.

5.1 SNAP : the movement (or jumping) of cursor measured with distance 

5.2 GRID : dots in workspace at some distance apart

5.3 ORTHO

5.4 POLAR

5.5 OSNAP : OBJECT SNAPPING / OSNAP is a technique, which helps you to select an exact point on the object. 

ENDPOINT, MIDPOINT, CENTER, NODE, QUADRANT, INTERSECTION, EXTENSION, INSERT, PERPENDICULAR, TANGENT, NEAREST, APPARENT INTERSECTION, PARALLEL, FROM, NONE, POINT FILTERS

5.6 OTRACK : OBJECT TRACKING, POLAR TRACKING

5.7 DUCS : Dynamic UCS or User Coordinate System

5.8 DYN: Dynamic Input

One can put the Dynamic input OFF by clicking on DYN button on the status bar.

When the dynamic input is ON, (1) the angle of rotation (2) the distance, (3) instructions, and (4) command are shown near cursor. 

5.9 LWT: Line Weight

5.10 COORDINATE WINDOW : Coordinates of a point

Cross hairs, Co-ordinate System, GRID & SNAP

Status bar : Status bar accommodates following buttons, namely, 'SNAP, GRID, ORTHO etc......'. Click on 'GRID' button on status bar and one will see small dots appear in the drawing area. The drawing area provides cross hairs, which are the two lines at right angles and the crossing point is a point of selection. The cross hairs are connected to mouse and the crossing point can be scrolled up-down and right-left. The two black arrows in the left corner of the drawing area indicate user the X and Y direction. This icon is called ' co-ordinate system icon's. The present co-ordinate system is the 'World Co-ordinate System' ( WCS). WCS / World Co-ordinate System : WCS or World Co-ordinate System is a basic co-ordinate system that is default in the CAD software. GRID :  An area covered with regularly spaced dots or lines to aid drawing. The grid spacing is adjustable. The grid dots are never plotted. Grid shall show one the dots at a specified distance.

Layout Settings

Basic setup of drawing : Layout preparation requires following commands.  ● Units : The format for display co-ordinates and measurement units. (i) Decimal (ii) Engineering (iii) Architectural (iv) Fractional (v) Scientific Use Units menu to change the units to Engineering or Architectural type. ● Limits The command LIMITS sets and controls the drawing boundaries. At the command prompt, type LIMITS and enter ON/OFF/<Lower left corner> <current> : [ Possible actions : (1) Specify a point (2) type ON and enter (3) type OFF and enter (4) press enter to terminate the LIMITS command] The LIMITS is used to set up the area of a drawing started from scratch or to change the area settings of an existing drawing. The default drawing area is 12 X 9 ( in inches). The drawing area provides cross hairs, which are the two lines at right angles and the crossing point is a point of selection. The cross hairs are connected to mouse and the crossing point can be scrolled up-down and right-left

Modify Menu : Part I

2. The MODIFY Menu The MODIFY Menu contains sub-menus or commands to modify the drawn object. 2.1 TRIM : TRIM command cuts the portion of the object, which extends beyond another object. At the command prompt, enter TRIM Select cutting edges : (Projmode = UCS, Edgemode = No extend) Select objects: Use an object selection method <Select object to trim> / Project / Edge / Undo : Select an object, enter an option, or press enter. 2.2 ERASE : ERASE is used for erasing or deleting the objects from the drawing. At the command prompt, enter ERASE Select objects : Use an object selection method. ● Other Methods of ERASING the objects : 1] Selecting a single object 2] Window Selection      A] Left to right selection window      B] Right to left selection window ( Crossing) 2.3 COPY : With COPY command one can copy set of objects to a different location. At the command prompt, enter COPY Select objects : Use an object selection method < Base point or displacement > /Multiple : Specif
