Unlocking the endless possibilities and power of DDD though the use of Algebraic Constraints, at the very least, standalone Algebraic constraints solutions can serve as saved calculations that might be repeatedly punched into your desktop calculator. In other cases it can replace those spreadsheets and give you direct access to complex calculations right in your design environment, saving window-switching multilple document management and tracking.
But the ultimate use is when assigning these outputs to Graphical Solutions for prototyping designs and generate final presentation output all in one shot.
