This procedure shows how to create MicroStation 3D DGN documents for export into MicroStation J (V7) and MicroStation V8 DGN files. See Exporting 3D Model Graphics to MicroStation, Exporting 3D Model Graphics to MicroStation.
-
Create a MicroStation 3D DGN component, and add a new package of components.
-
Right-click the MicroStation 3D DGN component, and select Setup from the shortcut menu.
-
Select the required MicroStation Version DGN file to generate. You can select Generate v7 DGN file, Generate v8 DGN file, or Generate Connect Edition DGN file.
-
Generate v7 DGN file is selected by default.
-
Both MicroStation v7 and v8 can reside on the same computer.
-
-
Select the appropriate seed file to use from the options available.
-
Select the view style you want to use to determine what objects are displayed in the document.
-
Create one or more drawing volumes to associate with the drawing view by switching to the Space Management task and using one of the Place Drawing Volume commands.
-
Right-click the MicroStation 3D DGN drawings component, and select the Create Drawing(s) Command to create the blank drawing.
-
Right-click the document, and click the Update Now Command to update the information displayed in the drawing.
You must place a Drawing type volume from the Space Management task before you can
update the drawing.
-
You can open the DGN file in MicroStation after it is updated. Select Open and the drawing component.
-
You can export DGN files by right-clicking a folder, component, or single document, and then selecting Save As on the shortcut menu.
-
The delivered seed files contain master units as m (meters) and feet ("). When exporting graphics to MicroStation Version v7 DGN file format, make sure the selected MicroStation Version v7 DGN seed file has one of the following labels as working units.

The size and measurement of the graphics is accurate only if the units present in the seed file are within the set of units listed in the previous table. Otherwise, the working units of the seed file are treated as meters. These labels are not case-sensitive.
-
The MicroStation DGN data reflects the clipping applied in 3D application and the style information defined in the graphic rule of the view style. No data is persisted on any of the model objects, but all objects are mapped to levels as specified by the graphic rule. If the graphic rule does not assign a level, the graphics are placed on level 1.
-
After a view style is selected on the Setup Dialog (MicroStation DGN Files), you can use the view style properties to add, edit, or remove filters that determine what objects are included in the document.
-
The Layer property in a graphic rule assigns objects to a DGN level. For the purposes of saving to a 3D DGN file, the software only recognizes levels 1 to 63. Other values, or an empty field, are interpreted as level 1.
