To Create a Nonrectangular Layout Viewport

You can create a new viewport with nonrectangular boundaries by converting an object
drawn in paper space into a layout viewport using the MVIEW command.

With the Object option, you can select a closed object, such as a circle or closed
polyline created in paper space, to convert into a layout viewport. The object that
defines the viewport boundary is associated with the viewport after the viewport is
created.

With the Polygonal option, you can create a nonrectangular layout viewport by specifying
points. The prompts are the same as the prompts for creating a polyline.

NOTE: When you want to suppress the display of the boundary of a layout viewport, you should
turn off the layer of the nonrectangular viewport instead of freezing it. If the layer
of a nonrectangular layout viewport is frozen, the viewport is not clipped correctly.
