Summary
When you attach a DGN file as an underlay, you link that referenced file to
the current drawing. Any changes to the referenced file are displayed in the
current drawing when it is opened or reloaded.
The Select Reference File dialog box (a standard file selection dialog box) is
displayed. Once you select a DGN file, the
Attach DGN Underlay dialog box
is displayed. After the file is attached, you can adjust and clip the underlay
through the
DGN Underlay Ribbon Contextual tab on page 536.
NOTE DGNATTACH is not limited to files with .dgn extensions. It supports all
DGN files, even those that do not have a .dgn extension.
If you enter -dgnattach at the Command prompt, options are displayed.
NOTE When a DGN file is attached as an underlay, its levels structure (layers) are
combined into a single layer. The DGN underlay is placed on the current layer.
To hide the DGN attachment, freeze the layer on which it was attached.
