Controlling the Visibility of DGN Underlay Layers

You can specify layer visibility of a DGN Underlay that is a referenced DGN file in a drawing.

1. Do one of the following:
   • On the ribbon, click Insert > Reference > Layers > DGN Underlay Layer Manager.
   • On the menu, click Format > DGN Layer.
   • Type LayersDGN.
2. In the graphics area, specify a DGN Underlay.
