Datalinks - Further Information

Designer enables any attribute within any AutoCAD drawing to be updated from the AVEVA Instrumentation Project Database. A DataLink is attached to each block's attributes in a Template file or Seed file as Extended Entity Data (Xdata). Extended Entity data is invisible in AutoCAD, so the Datalinks will not effect the CAD file visually.

Note: DataLink definitions are invisible within the drawing file and can only be accessed by an applications program such as Designer (or AutoLisp/Visual Basic etc.).

An AVEVA Instrumentation DataLink represents a data value that is replaced by the actual project data when updated by Designer. When a drawing is updated by Designer, all AutoCAD attributes that contain a DataLink are automatically updated with the current data from the AVEVA Instrumentation project database. This data could include title block and revision information as well as engineering, wiring or other project data.
