Ignore Duplicate Names Ignores any duplicate named objects, such as layer
names or dimension styles, in the DGN file and gives precedence to the existing
definition for duplicates.
You can also control the default settings using the DGNIMPORTMODE system
variable.
NOTE For the correct display of linetypes, the MicroStation RSC (resource file)
that is referenced by the DGN file must be available on your computer in a valid
AutoCAD Support File Search Path when you import or attach the DGN file. If the
resource file is not found, you will get an error message. You can define a search
path location in the OPTIONS command, Files tab. You can add a path to the
AutoCAD Support File Search Path node. You can also copy the RSC file to an
existing Support File Search Path.
Select a Design Model from the DGN file
The DGN design model that you select is imported into the model space of
your current DWG file.
V8 DGN files might contain multiple design and sheet models. A DGN design
model is equivalent to model space, and a DGN sheet model is equivalent to
paper space. Because a DWG file can have only one model space, you need
to select the design model in the DGN file that you want to import.
If a design model is selected and is referenced into a sheet model, then the
sheet model is also converted as one or more layouts in the DWG file. Only
the sheet models that reference the primary design model are imported. These
sheet models are translated to paper space layouts, and will include layout
viewports that display each reference to the primary design model.
External DGN References
Controls how DGN references are handled in a DWG environment.
Any DGN files are supported as references. These file types include, but not
limited to, these extensions: .dgn, .dwg,.cel,.s,.h, .cgm,.rdl,.d files. However, DXF
files are not supported and are ignored.
Translate References to Blocks or Xrefs
Converts DGN references to blocks when importing into a current drawing
and to xrefs when importing into a new drawing.
All referenced DGN design models, including nested references, are converted
into blocks or attached as xrefs in model space.
The relationship of nested references is maintained. Nested references within
a DGN design model that reference the primary file are called circular
