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.

1. Click View > Viewports > Polygonal viewport
2. Specify points to create a nonrectangular layout viewport. The prompts are the same as the prompts for creating a polyline.
3. Click View > Viewports > Object
4. 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.

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.
