IsoDraw - Generate Callouts from XML BOM File

Hi,

Can anyone explain how to generate a structurally valid XML BOM file used to generate callouts in IsoDraw 7.3?

• What is the source of the XML BOM file? where is it exported from?
  • IsoDraw Object List?

• Windchill Structure?
• CAD Model?
• Our IsoDraw files are stored in Windchill. Do the BOM XML files need to be stored in Windchill at the same location as the illustration?

Regards,

Jon
