Adjust DGN Underlay Appearance and Clipping Boundaries
After attaching a DGN underlay, you can adjust the appearance of the underlay or set up clipping boundaries to focus on the specific part of the underlay.
Aside from using the Properties palette to edit the position, scale, and rotation of a DGN underlay, you can also modify the fade, contrast, and monochrome settings of a DGN underlay.
You can clip the display of a DGN underlay in a drawing with a rectangular or polygonal clipping boundary.
You can control the visibility of the frame that represents the extents of the DGN underlay or the visibility of the frame that is defined by the clipping boundary.
