21.11 VIEW PORTS
The rectangular portion of the graphics screen in which a drawing is displayed is called the
view port. The screen may be divided into multiple view ports and individual controls can be
exercised on each view port. One can have upto 4 view ports on screen at once (Fig. 21.15).
AutoCAD Release 13 can display 16 view ports maximum on the computer monitor. Each view
port can display a different view of the drawing. Panning and zooming can be performed in each
view port independently. View ports are useful for checking the correctness of a design. One
can edit the drawing in one view port and immediately see the results in all the view ports.
Though several view ports can be displayed on the screen, one can work in only one of the
view ports at a given time, known as current view port. This active view port is recognized by a
heavy border. The cursor will be in the form of cross hairs when it is inside the current port and
will be an arrow outside it. Various views may be displayed in these view ports, such as: 3D
view, top view, side view, front view, etc.
