Viewing Zoom in on a drawing to better control the order of overlapping objects. The easiest way to change your view is by using the mouse wheel. • Zoom in or out by rolling the wheel. • Pan a view in any direction by holding the wheel down while moving your mouse. • Zoom in on a specific area for greater detail holding your mouse over the area and clicking the wheel twice..

Module 1. TOPIC 2 :- Basic Drawing commands in Auto Cad.

The Mouse Most people use a mouse as their pointing device, but other devices have equivalent controls. pan and zoom select objects shortcut menus specify locations.

Lines The line is the most basic and common object in AutoCAD drawings. To draw a line, click the Line tool. —Home Insert Line Polyline Circle Draw Annotate Arc Alternatively, you can type LINE or just L in the Command window, and then press Enter or the Spacebar. LINE Specify first point: To specify the starting point for this line, you would type in the coordinates 0,0. It is a good idea to locate one corner of your model at 0,0, which is called the origin point. To locate additional points, you could specify additional X,Y coordinate locations in the drawing area, however more efficient methods for specifying points are available, and will be presented in the Precision topic. After you specify the next point, the LINE command automatically repeats itself, and it keeps prompting you for additional points. Press Enter or the Spacebar to end the sequence..
