Below is a view of a rolled-out bottom plate, for a planing hull.
Naturally, you can output your result to a DXF file, for further engineering work.
If your design includes a rounded stem, this is included faithfully in the calculated surface. The program uses the established Kilgore algorithm, and many trials by Hullform users have confirmed that the developed surfaces are not only accurate, but also relatively simple to generate.
You can also plot and write out the rolled-out form of the transom or any defined stringer (See Stringer Calculations)
