Driver Options for DGN 8
You can set the following options when importing DGN 8 files:
DescriptionOption
Choose Geometry to group incoming objects by entity type.
Choose Level or Level Names to group them by their DGN
Group Elements By
level or level name. Only levels that contain elements will be
imported.
By default, cells are converted into blocks, maintaining the
cell grouping. You can choose to convert the cells to points
Cell Expansion
instead. You can also explode the contents of the cells into
their component parts, but the explosion is one level deep
only.
Each DGN 8 file can define Sub units and Master units. Specify
which of these units in the DGN 8 file matches the default
Coordinate Units
unit in the AutoCAD Map 3D map. For example, if the default
unit in your AutoCAD Map 3D map is meters, and meters are
the Sub unit in the imported file, select Sub.
When you import the file, one Master or Sub unit (whichever
you choose) will become one drawing unit in your AutoCAD
Map 3D map. The Unit Ratio value indicates the ratio between
the Master and Sub units. For example, if the ratio is 1:12 (as
it would be for Feet/Inches), imported object coordinates will
be scaled 12 times bigger if you select Sub.
NOTE When you import or export a DGN file with a master
unit of Imperial feet, AutoCAD Map 3D converts the master
unit from feet to meters. In addition, it does not recognize
any sub-unit selection during the import or export process.
Select the options to use during import. For example, select
Explode Complex Strings to return each component of a
Element Expansion
complex chain as its own feature (no feature will be returned
for the complex chain as a whole). Otherwise, all elements
of the complex chain merge into a single linear feature, any
