Use of ICT for e- content development during COVID - 19

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. One c

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

■ 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.
