Prepare a DGN for an Teigha® Technology Translation

Select the Model

Import-DGN currently imports only the currently selected model in a dgn8 file. Make sure that this is set correctly.

Units

Import-DGN attempts to extract the units information from the dgn files and is usually successful. In some cases, particularly when reading a dgn7 format file, Import-DGN does not make the same assumptions as MicroStation. In these cases, either adjust the scale factor to correct the translation, or use MicroStation to upgrade the file to dgn8 format, and make sure that the working units are set correctly.

Note:
Check that the dgn file units are set correctly.

Global Origin

Import-DGN (unlike the Basic facilities) currently ignores the Global Origin set in the dgn file. Shifts can be applied to the model produced to position it in the appropriate position in space.

Large Cells

Some dgn files are structured with a highly nested cell structure, with very few top-level elements. Import-DGN uses the top-level elements to help structure the model in the Design macro, so if a large model is composed of a very few cells with complex contents, it is best to use the MicroStation Drop tool (using the drop complex option) to drop these until the top-level elements are no more complex than the user wants to put into a single sub-equipment or substructure element in Design.

Feature Solids

The current release of Import-DGN cannot translate some MicroStation Feature Solids. The MicroStation Solid Utilities: Convert to Solid tool can be used to convert these to Smart Solids.
