Clipping Viewports on Sheets

The ClipViewport command lets you clip the display of Viewports on the current Sheet at irregular shapes.

When you create a Viewport on a Sheet, it has a rectangular boundary shape by default. Use the command to replace the rectangular shape, either by specifying a closed entity as the new boundary, or by drawing a new polygonal boundary by pointing to the graphics area.

To clip a Viewport on a Sheet by specifying a clipping entity:

1. Activate a Sheet tab so you are in SheetMode.
2. Click Modify > Clip > Viewport (or type ClipViewport).
3. Select the Viewport to clip.

   Note: You cannot clip a Viewport which was created with the Entity option.

4. Select the entity that defines the clipping boundary. You can select a Circle, Ellipse, closed PolyLine, or closed Spline.

   The selected boundary clips the Viewport and replaces the rectangular boundary.

To clip a Viewport on a Sheet by pointing to a polygonal shape:

1. Activate a Sheet tab.
2. Click Modify > Clip > Viewport (or type ClipViewport).
3. Select the Viewport to clip.

   Note: You cannot clip a Viewport which was created with the Entity option.

4. Specify the Polygonal option.
5. Select the first point of the irregular shape.
6. Continue to select points to define the boundary or specify an option:
   • Arc: Draw arc segments of the shape. You can use the arc options as you can in the PolyLine command.
   • Close: Closes the polygonal shape. The new boundary clips the Viewport.
   • Length: Draws a straight segment of a specified length in the same direction as the previous segment (tangentially if it was an Arc).
   • Undo: Removes the previous segment.
7. Press Enter to close the polygonal shape.

   The new boundary clips the Viewport.

  You cannot use the ClipViewport command in the Model tab.
