Usage Notes

• This is a good first query to understand the drawing contents
• path, fingerprintGuid, and dbmod are the minimum identity check before a separately approved write
• isSavedAndClean is true only for a named drawing with DBMOD=0
• Coordinate system code follows EPSG or Autodesk format
• Units can be Meter, Foot, etc.
