DGNOSNAP
Determines whether object snapping is active for geometry in DGN underlays
that are attached to the drawing.
Detach Underlay Files
Underlays that are no longer needed can be detached from a drawing file.
When you detach an underlay, all instances of the underlay are removed from
the drawing, and the linking path to the file is removed.
To hide the display of an underlay temporarily, you can unload it rather than
detach it. This action preserves the underlay location for reloading later.
NOTE Erasing an individual instance of an underlay is not the same as detaching
it. An underlay must be detached to remove the link from your drawing to the
file.
To detach an underlay
1 Click Insert tab Reference

2 In the External References palette, in the File References pane, select the

3 Right-click on the underlay and click Detach.
The underlay is no longer linked to the drawing file. All instances of the
underlay are removed from the drawing.
