Data with built-in features or variations are visually approximated. For
example, text and dimensions might have specialized formatting, and
color definitions might be customized.
Some data cannot be translated completely. For example, product-specific
features such as data fields or dynamic blocks can be represented visually
but not behaviorally.
See the DGNIMPORT Conversion Table for specific details about the scope of
importing MicroStation objects and other data.
See the DGNIMPORT Unit Mapping Table for specific details about unit
conversions when importing MicroStation objects.
Recommendations
To optimize the data transfer from the MicroStation
®
DGN file format, request
that the creator of the MicroStation drawings consider the following
recommendations:
Create a separate DGN file for each design model
Do not reference sheet models from design models
Minimize the use of custom objects and other data unique to MicroStation
Use ByLevel for color, line style, and weight properties
Use simple line styles as much as possible
Use simple patterns and pattern styles
Use TrueType text fonts rather than SHX text fonts
Use defined styles for dimensions and text rather than a none style
Use simple dimension styles if possible
Use shared cells as opposed to normal (library) cells
Work primarily in one format, DWG or DGN, rather than switching back
and forth
When importing a DGN file, specify the conversion units (master units or
sub-units) based on the DWG file's drawing units. For example, if you receive
a DGN file with master units set to meters, and sub-units set to millimeters,
and you need the drawing units of the DWG file to be in meters, then select
