For some DWG files, symbology is missing in the table of contents, and the theme does not appear anywhere when the view is displayed.
Solution or Workaround
Do one of the following:
- Open the file in AutoCAD and save it as a DXF file type.
- Open the file in AutoCAD and convert it into a blocked DWG.
Import the DXF or blocked DWG file into ArcView.
