In addition to simple dialog-box based title block selection and placement, DrafTools allows users to define 'smart' attributes in their title blocks which may be programmed to calculate their default value during insertion. DrafTools is an old unsupported freeware AutoCAD add-on for AutoCAD R14 and AutoCAD 2000 that facilitates drawing setup by managing custom title blocks and automatically setting system variables based on the drawing scale selected during title block insertion.
