The general use cases are typically AutoCAD users with a set of floor plans where the content of single or multiple sub-spaces within a floor-plan change status or purpose on a relative frequent basis. An update of the graphical infromation in the floor plans is therefore needed requently, and it is not econmically feasible to update the floor plans in the CAD authoring tool. The graphical content that changes is either available in a DB application, or is obtained by other means. One recommended extraction tool is: LinkList/XML

The core use-cases are:

• Add New Entities
• Modify Existing Entities
