• Company has existing database with CAFM information for office buildings
• Drawings are done in AutoCAD
• Each room in each building is identified via a unique block name
• The AutoCAD file has the graphical information. The database information is stored in an external file, crossreference via the AutoCAD block name
• Each room can have zero, one or many pieces of information associated with it

The user has existing AutoCAD drawings that define each "room" or "area" by a unique polyline. Their external database uses the AutoCAD entity handles to uniquely identify the polyline or insert that defines the area.

The user need to change the color, haching and/or linetype of the existing polyline as the uses of the rooms changed. They also want to add text within the area to explain the area use, add hyperlinks to link between the drawing and other drawings or web pages, and to define database linkages for the area.
