references. AutoCAD resolves these circular references by creating a block and
insering it into the original primary DGN file.
Design model references to sheet models, and sheet model references to other
sheet models are not supported and are ignored. Unique names for references
are generated by appending the model name to the design file name separated
with a dash (-). If necessary, the resulting block names are truncated and one
or more of the last characters might be replaced with numerals to make the
file name unique.
With the following set of options, you can choose whether or not to overwrite
external reference files:
■ Prompt to Overwrite
■ Overwrite without Prompting
■ Do Not Overwrite
NOTE If the folder that contains the DGN file is read-only, then any DWG xrefs
will be created in the My Documents (Windows XP) or Documents (Windows Vista
and Windows 7) folder.
NOTE If you are importing a DGN file that uses custom line styles and those line
styles are defined in an external .rsc file, then the .rsc file needs to be included in
the AutoCAD support path.
Ignore All External References
Referenced DGN and DWG files that are external to the specified DGN file are
not included in the resulting DWG file.
If the DGN file has self references or references to other design models
contained within the DGN file, these references are included.
Attach as DGN Underlay
All DGN external references in the DGN file are imported as DGN underlays
in the resulting DWG file. Referenced DWG files remain xrefs when imported.
NOTE New DWG files are created in this process. These new DWGs are not
automatically deleted.
Conversion Units
Select the appropriate conversion units for the translation. The imported DGN
file contains working units (imperial or metric) called master units and sub-units.
The selected working units (master units or sub-units) are converted
one-for-one into DWG units.
