Underlay and Image Prompts

The following prompts are displayed.

On

Turns on clipping and displays the underlay cropped to the previously defined boundary.

Off

Turns off clipping and displays the entire PDF underlay and frame.

If you crop the underlay again while clipping is off, clipping automatically turns
on. You are prompted to delete the old boundary even when clipping is off and the
clipping boundary is not visible.

Delete

Removes a predefined clipping boundary and redisplays the full original underlay.

New Boundary

Defines a rectangular or polygonal clipping boundary, or generates a polygonal clipping
boundary from a polyline.

NOTE: You can only create a new clipping boundary for an underlay when the old boundary
is deleted.

Select Polyline

Defines the boundary with the selected polyline. The polyline can be open but must
consist of straight line segments and cannot intersect itself.

Polygonal

Defines a polygonal clipping boundary with three or more points that you specify for
the vertices of a polygon.

Rectangular

Defines a rectangular boundary with the points that you specify for opposite corners.

Invert Clip

Inverts the mode of the clipping boundary: objects are cropped either outside the
boundary or inside the boundary.

External Reference Prompts

The following prompts are displayed.

Select objects: Use an object selection method and press Enter when you finish selecting objects

On

Displays the cropped portion of the external reference or block in the current drawing.

Off

Displays all of the geometry of the external reference or block in the current drawing,
ignoring the clipping boundary.

Clipdepth

Sets the front and back clipping planes on an xref or block. Objects outside the volume
defined by the boundary and the specified depth are not displayed. Regardless of the
current UCS, the clip depth is applied parallel to the clipping boundary.

• Front Clip Point. Creates a clipping plane passing through and perpendicular to the clipping boundary.
• Distance. Creates a clipping plane the specified distance from and parallel to the clipping
  boundary.
• Remove. Removes both the front and back clipping planes.

Delete

Removes a clipping boundary for the selected xref or block. To temporarily turn off
a clipping boundary, use the Off option. Delete erases the clipping boundary and the
clipdepth. The ERASE command cannot be used to delete clipping boundaries.

Generate Polyline

Automatically draws a polyline coincident with the clipping boundary. The polyline
assumes the current layer, linetype, lineweight, and color settings. Use this option
when you want to modify the current clipping boundary using PEDIT and then redefine
the clipping boundary with the new polyline. To see the entire xref while redefining
the boundary, use the Off option.

New Boundary

Defines a rectangular or polygonal clipping boundary, or generates a polygonal clipping
boundary from a polyline.

NOTE: You can only create a new clipping boundary for a selected XREF underlay when the
old boundary is deleted.

• Select Polyline. Defines the boundary with the selected polyline. The polyline can be open but must
  consist of straight line segments and cannot intersect itself.
• Polygonal. Defines a polygonal clipping boundary with three or more points that you specify for
  the vertices of a polygon.
• Rectangular. Defines a rectangular boundary with the points that you specify for opposite corners.
• Invert Clip. Inverts the mode of the clipping boundary: objects are cropped either outside the
  boundary or inside the boundary.

Viewport Prompts

Clipping Object

Select the viewport to crop.

Polygonal

Draws a clipping boundary. You can draw line segments or arc segments by specifying
points.

The descriptions of the Next Point, Arc, Close, Length, and Undo options match the
descriptions of the corresponding options in the PLINE command.

Delete

Deletes the clipping boundary of a selected viewport. This option is available only
if the selected viewport has already been clipped. If you crop a viewport that has
been previously clipped, the original clipping boundary is deleted, and the new clipping
boundary is applied.
