Import into Current Drawing

Inserts the contents of the DGN file into the current DWG file.

Prefix Dependent Definitions

Adds the DGN file and model name as a prefix to the incoming object’s name. If the
prefixed name results in a new name conflict, then an incremental number is appended
to the name.

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.

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 references. AutoCAD
resolves these circular references by creating a block and inserting 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 7 and Windows 8) folder.

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.

Master Units

Specifies that one master unit of the imported DGN file converts to one DWG drawing
unit.

Sub Units

Specifies that one sub-unit of the imported DGN file converts to one DWG drawing unit.

Explode Text Node to Text Elements

Text node elements in a DGN file are multiple lines of text stored as one element, and are similar to
MTEXT objects. Check this option to maintain text which follows a path.

When cleared, multiple lines of text are maintained as a single multiline text object.

When checked, multiple lines of text are separated into individual text objects. Select
this option to maintain visual fidelity when you import a DGN file that includes text
created along a curved path. The first character determines the location and rotation
of the text object.

Translate DGN Properties to DWG Properties

Selects and manages the mapping setup used on the current DGN import.

Select Mapping Setup

Displays the currently defined mapping setups.

Standard is the default mapping setup which extracts data from the drawing being exported
and applies an automatic mapping to DGN layers, linetypes, lineweights, and colors,
as shown in the mapping preview.

Setup Description

Displays the description of the selected mapping setup.

Mapping Setups

Opens the DGN Mapping Setups dialog box where new mapping setups can be created and
existing mapping setups can be renamed, modified, or deleted (DGNMAPPING).

Mapping Preview for Setup: Standard

Lists all properties of both the imported DGN file in the DGN column and the selected
mapping setup in the DWG column.

NOTE: External reference files properties are not listed in a mapping preview.
