When you export views and sheets to DGN, Revit objects and features are mapped to their MicroStation counterparts where applicable.
| Revit | MicroStation | Notes |
|---|---|---|
| Geometric Elements | Geometric Elements |
Includes detail lines, model lines, and 2D presentations of Revit elements. If you need to export 3D objects to DGN, you can use the same algorithm used in Revit 2012 by adding the UseVersion2012DGN key to the Revit.ini file.) |
| Colors | Colors | Colors are matched as closely as possible. Categories set to export with index color are translated directly to the DGN color index. If true color is used and a direct match of RGB values is available in the DGN color index, the colors are also mapped directly. If a true color match is not available, an RGB value is added to the DGN color index. |
| Line Patterns | Line Styles | Custom linetypes are unsupported and could produce unexpected results. |
| Families | Cells | Families are exported as shared cells. |
| Model Text, Text Notes | Lines, Text, Text Styles | Model text is exported as lines; text notes are exported as text. |
| Dimensions, Dimension Styles | Dimensions, Dimension Styles | The size, spacing, style, and shape of dimensions may vary slightly. The correct dimension values are always maintained. |
| Raster Images | Raster Images | BMP, TIF, PNG, and JPG file types are supported. |
| Links | DGN References | Depending on the export option specified, referenced RVT and DWG files are either converted into DGN files or combined into a single DGN file as cells. |
| View | DGN Design Model | The view in a Revit project file is converted into a DGN file. |
| Sheets | DGN Sheet Model | Upon export to V8, sheets are converted into sheet models in the DGN file. Because V7 only supports one model, several DGN files may be exported: one for the model and others for the sheet views in the Revit project file. |
| AEC Objects | Imported objects from AutoCAD Architecture are not supported. |
