Creates and controls layout viewports.
In a layout, you can create as many viewports as you want, but only up to 64 viewports can be active at one time (see MAXACTVP). Objects in model space are visible only in active viewports. Viewports that are not active are blank. Use the On and Off options to control whether viewports are active.
The following prompts are displayed.
Specify corner of viewportor [ON/OFF/Fit/Shadeplot/Lock/Object/Polygonal/Restore/LAyer/2/3/4].
Makes a selected viewport active. An active viewport displays objects in model space. The MAXACTVP system variable controls the maximum number of viewports that can be active at one time. If your drawing contains more viewports than the number specified in MAXACTVP, you must turn one off to make another one active.
Makes a selected viewport inactive. Objects in model space are not displayed in an inactive viewport.
Creates one viewport that fills the layout to the edges of the printable area. When the paper background and printable area are turned off, the viewport fills the display.
Prevents the zoom scale factor in the selected viewport from being changed when working in model space.
Specifies a closed polyline, ellipse, spline, region, or circle to convert into a viewport. The polyline you specify must be closed and contain at least three vertices. It can be self-intersecting, and it can contain an arc as well as line segments.
Creates an irregularly shaped viewport using specified points.
Adds arc segments to the polygonal viewport.
For a description of the options for creating arc segments, see the Arc option in PLINE.
Divides the specified area into three viewports.
The Horizontal and Vertical options split the specified area into thirds. The other options split the area into three viewports: one large viewport and two smaller ones. The Above, Below, Left, and Right options specify where the larger viewport is placed.
