Clipping DGN Underlays

You can display only part of a DGN Underlay. The entity is clipped at a boundary you create or specify.

You can create one clipping boundary per DGN Underlay.

To clip DGN Underlays:

  1. Specify the DGN Underlay to clip.
  2. On the contextual ribbon, click Reference Manager > Clip.
  3. Specify the DGN Underlay to which you want to apply a clipping boundary.
  4. Specify an option:
    • On. Turns the clipping boundary on to display only the portion of the DGN Underlay inside the clipping boundary.
    • Off. Turns the clipping boundary off to display the DGN Underlay entirely. The clipping boundary is retained so you can activate it again.
    • Delete. Removes the clipping boundary.
    • Create Boundary. Creates a new clipping boundary. If a clipping boundary already exists for the DGN Underlay, you are prompted to delete the old boundary. Specify an option:
      • Select polyline. Uses an existing PolyLine as a clipping boundary. Arc segments are straightened.
      • Polygonal. Lets you define a polygonal shape as a clipping boundary by specifying points.
      • Rectangular. Lets you define a rectangular clipping boundary by specifying two opposite points.
