Export to 3D DGN
You can export selected parts or the whole model to 3D DGN. You can use either the older v7.0 export or the newer v8.0 export.
Export to 3D DGN v8
-
3D DGN export v8 uses Teigha libraries.
-
The surface presentation of the parts is exported. Bolt holes are not included in the export.
-
You can export objects relative to the model origin, to the base point you define, or to the work plane.
-
You can export in layers by name, phase or any template attribute or user-defined attribute.
-
Colors can be exported by class or by stored object group representation.
-
You can export all objects or selected objects. You can use the Select objects in assemblies and Select objects in components selection switches for selecting the objects to export. You can export selected parts in an assembly when you use the Select objects option and Select objects in assemblies and Select objects in components when you select the parts. If you do not select a part but an assembly, the highest level of assembly parts will be included in the export.
Create object group color representations
If you want to use object group color representations in the export, you need to create the object groups first, set the colors for the object groups and save the representation settings. Note that the transparency setting is not included in the export.
Create base points
If you want to export objects relative to a base point, you need to create a base point in your model. For more information, see Base points.
Export to 3D DGN v7
-
The 3D DGN v7 export supports parts only.
-
In 3D DGN v7 export, you can only export to the model origin. Changing the work plane has no effect to export.
Advanced options related to 3D DGN export
If you have tubular parts in your model and you want to reduce the size of the DGN files or the complex display in the rendered views, you can use the following advanced options to control this:
