Design-to-Design Comparison Graphics feature allows you to "remember" all the performance characteristics of your base design, then input your design change(s) and view how the new results compare. The D-to-D feature makes it EXTRA “Graphically” EASY to see exactly how the design changes affect performance in all areas.

Make one design change at a time, or make several changes to design variables, and then see BOTH the new performance data and the previous ‘remembered’ performance data - both are presented, making it easy to compare the results of the 2 design.
