Saving DGN Elements to DWG Files
The table summarizes what happens to elements in DGN files when they are saved to DWG files.
| DGN element | DWG objects after DGN to DWG conversion |
|---|---|
| Cells | Blocks |
| Classes | Elements in construction, pattern, or linear patterned class elements can be saved to a layer or can be invisible entities. |
| Colors | Automatically converted to use AutoCAD's fixed color table. To explicitly control how each color in the DGN file will appear in the DWG file, use the Remap capability. |
| Design Models | The default design model is saved to model space. Non-default design models can be saved to additional DWG files or drawing layouts (paper space). |
| Enter Data Fields | Enter Data Fields that are not attached to cells are converted to text. Enter Data Fields in cells are converted to attribute labels. The labels are assigned default names that cannot be modified. |
| Fonts | TrueType and *.SHX fonts are supported by both programs.
MicroStation
fonts can be converted to AutoCAD fonts when the file is saved to DWG. To explicitly control how each font will appear in the DWG file, use the Remap capability. |
| Levels | Layers. Symbology (color, line style, line weight) ByLevel settings are converted to BYLAYER settings. To define how levels are converted to layers, use either the Save As DWG/DXF dialog or the Remap capability. |
| Line Styles | Line styles are saved to linetypes. For line styles that are not compatible with AutoCAD, use the Drop UnSupported LineStyles to Components option on the Save As DWG/DXF Options dialog. To explicitly control how each line style in the DGN file will appear in the DWG file, use the Remap capability. |
| Line Weights | Automatically converted to AutoCAD lineweights. To explicitly control how line weights in the DGN file are converted to lineweights in the DWG file, use the Remap capability. |
| References: Attachments to Non-Default Models | If non-default models are saved to separate DWG files, then references to these non-default models are saved to XREF inserts that reference the DWG files. If non-default models are saved to paper space or ignored, then the references must be merged to the output file to be included in the DWG output. |
| References: Masked Attachment | To be included in the DWG file, clipping masks applied to references must be merged to the DWG output file. |
| References: Self-Attached | To be included in DWG file, self-attached references must be merged to the DWG output file. |
| References: Standard External Attachments | To be included in the DWG file, standard external attachments can be merged into the DWG output file or become XREFs. |
| Sheet Models | Drawing Layouts (paper space) |
