AutoCAD

AutoCAD, developed by Autodesk Inc., is the most popular PC – CAD system available in the market. This design package is a general purpose computer aided design and drafting application for your computer. The speed and ease with which a drawing can be prepared and modified using a computer offer a phenomenal advantage over hand preparation. Here I’m going to mention a few of the applications for which AutoCAD is being used today:- •Architectural drawings of all kinds.

Interior designs on facility planning.
Drawings for Electronics, Chemical, Civil, Mechanical, Automotives and Aerospace engineering applications. •Theatre set lighting designs.
Line drawing for the Fine Arts, Textiles, Fashion and Dress designing. Some other CAD packages developed by the same company are:- •Auto Shade
Auto Flix
Auto Ketch
Animator
3D Studio

AutoCAD Screen

Various components of the initial AutoCAD screen are drawing area, command window, menu bar, several toolbars, model and layouts, and the status bar (Fig. 1). A title bar that has AutoCAD symbol and the current drawing name is displayed on top of the screen.

SCREEN COMPONENTS

Drawing Area
The drawing area covers the major portion of the screen. Here we can draw the objects and use the commands. To draw the objects, we need to define the coordinate points, which can be selected by using our pointing device

Command Window

Figure 2 Command Window
The command window at the bottom of the drawing area has the command prompt where we can enter the commands. It also displays the subsequent prompt sequences and the messages. We can change the size of the window by placing the cursor on the top edge and then dragging it

Application Status Bar

Figure 3 Application Status Bar
The Status Bar is displayed at the bottom of the screen (Fig. 3). It contains some useful information and buttons that will make it easy to change the status of some AutoCAD functions. We can toggle between on and off states of most of these functions by choosing them. Coordinates

The coordinates information is displayed on the left corner of the Status Bar. We can select this coordinate button to toggle between on and off states. If the COORDS system variable controls the type of display of coordinates.

Snap Mode
The snap mode allows you to move the cursor in fixed increments. If snap mode is on, the Snap Mode button is chosen in the Status Bar; otherwise it is not displayed.

Grid Display
The grid lines are used as a reference lines to draw objects in AutoCAD. If the Grid Display button is chosen, the grid lines are displayed on the screen.

Ortho Mode
If the Ortho Mode button is chosen in the Status Bar, we can draw lines at right angles only.

Polar Tracking
If we turn the polar tracking on, the movement of cursor is restricted along a path based on set as the polar angle settings. Choosing the Polar Tracking button in the Status Bar turns it on. Remember that turning the polar tracking on, automatically turns off the ortho mode.  

Object Snap
When the Object Snap button is chosen in the Status Bar, we can use the running object snaps to snap a point.

Allow/Disallow Dynamic UCS
Choosing the button allows or disallows the use of dynamic UCS. Allowing the dynamic UCS ensures that the XY plane of the UCS got dynamically aligned with the selected face of the model.
