class AcDbViewportTableRecord : public AcDbAbstractViewTableRecord;

Objects of this class represent viewport arrangements when TILEMODE == 1 within AutoCAD (the ViewportTable and its records are not used when TILEMODE == 0). The AcDbViewportTable (referred to in AutoCAD and DXF documentation as the VPORT table) is the container or owner of objects of this class.
The AcDbViewportTable is unique in that it can contain multiple AcDbViewportTableRecords with the same name. This is necessary because when a multiple viewport configuration is saved, all viewports in the configuration must share the name, but each viewport has its own AcDbViewportTableRecord created to save the data for that viewport.
