Working with References That Will Be Saved to DWG Files
When you are working with a DGN file that will be saved to a DWG file:
- Use settings on the Save As DWG/DXF Options dialog to control how MicroStation references will be handled in the DWG file format.
- Do not attach the active model to itself as a reference (self-reference), since the DWG file format does not support this type of reference.
- Use MicroStation's Live Nesting option, since it is compatible with AutoCAD's settings.
- You can set options in MicroStation to create references that can be saved to AutoCAD overlay attachments.
The default Xref Block
insert layer for a DGN reference attachment saved in the DWG file is the layer
named
"0."
To override the default insert layer for reference attachments, set the configuration variable MS_DWGINSERTLAYER to the desired layer name. For example, assigning MS_DWGINSERTLAYER to "MSINSERT" results in the assignment of inserts to the layer "MSINSERT". If this layer does not exist, it will automatically be created.
MS_DWGINSERTLAYER is used to override the default insert layer for normal (unshared) cells as well as reference attachments.
