You can use a clipping
boundary to clip an underlay.
You
can define part of an underlay that you want to display and plot
by setting up a clipping boundary with DGNCLIP, DWFCLIP, PDFCLIP,
DGNCLIP, IMAGECLIP, VPCLIP, and XCLIP. The clipping boundary can
be a closed polyline, rectangle or a polygon with vertices within
the overall extents of the underlay. Each instance of an underlay
can only have one clipped boundary. Multiple instances of the same
underlay can have different boundaries.
Following is an example
of an underlay with insets showing polygonal (l) and rectangular
(r) clipping boundaries:
When the clipping boundary
is no longer needed, you can delete the clipped boundary from the
underlay and the underlay is displayed with its original boundary.
You can also invert the area to be hidden inside or outside the clipping
boundary. With grips located at the midpoint on the first edge of the
clipping boundary, you can invert the display of the clipped reference inside
or outside the boundary.
You can control the way
clipping boundaries and grips display with the clipping frame system
variables. The clipping frame system variable are FRAME, PDFFRAME, DGNFRAME, DWFFRAME, XCLIPFRAME, and IMAGEFRAME.
To clip an underlay
- Click the bounding box of an underlay
to select it.
- Click Contextual tab
Clipping
panel Create
Clipping Boundary.
- At the command prompt, Enter s (Select
Polyline), p (Polygonal), r (Rectangular),
or i (Invert Clip) and then, draw
the specified boundary on the underlay.
To draw a boundary by
selecting a polyline, draw or overlay a polygonal shape created
with a polyline on the underlay. Then, click Create Clipping Boundary
and select the polyline to create a boundary.
To draw a polygonal boundary,
you are prompted to specify consecutive vertices. To finish drawing
a polygon, press Enter or right-click anywhere in the drawing area.
To specify a new boundary
on a clipped underlay
- Select a clipped underlay.
- Click Contextual tab Clipping
panel Create
Clipping Boundary.
- Enter y (Yes) to delete
the old boundary.
- At the command prompt, Enter s (Select
Polyline), p (Polygonal), r (Rectangular),
or i (Invert Clip) and then, draw
the specified boundary on the underlay.
To draw a boundary by
selecting a polyline, draw or overlay a polygonal shape created
with a polyline on the underlay. Then, click Create Clipping Boundary
and select the polyline to create a boundary.
If you are drawing a
polygonal boundary, you are prompted to specify consecutive vertices.
To finish drawing a polygon, press Enter or right-click anywhere
in the drawing area.
To edit the existing boundary
on a clipped underlay
- Select a clipped underlay.
- Click one of the corner grips and drag
it to a new location.
- Click again to set the corner grip.

To show or hide the clipped
portion of an underlay
- Select the clipped underlay you want
to show or hide.
- Right-click, and click Properties.
- Scroll to Misc and select Yes or No for
the Show Clipped option.
