Summary
The clipping boundary determines the portion of a DGN underlay outside the
boundary that is hidden. The visibility of the clipping boundary is controlled
by the
DGNFRAME on page 1433 system variable.
The boundary you specify must be in a plane parallel to the DGN underlay.
TIP Use the generic CLIP on page 211 command to clip images, external references,
viewports, and underlays.
