When you import AutoCAD drawings that contain text, you can map the AutoCAD SHX fonts to TrueType fonts so they appear correctly in Vasari. You can map to any of your existing fonts.
To map TrueType fonts
This file resides in the following location: %ALLUSERSPROFILE%\Autodesk\Vasari 2014
You do not need to restart Vasari for the font mapping to take effect. If you have already imported the file, you will need to import it again.
