This is probably not intuitive enough for the general public. A good example of the sections is the BNC-3ET. Bill lets you select the shoulder, one section and an optional additional shoulder for transitions. We had to expand this for up to 10 different sections on some of our cones. The Bezier is the most complex of the shapes. Each has a beginning diameter, ending diameter and two contro points to "warp" the line between the two. Many of the Estes nose cones and all the Centuri plastic nose cones use the Bezier since they do not fit any of the standard shapes. A standard Ogive just uses one section.

The Load button starts over with the nose cone entered. The Refresh button modifies the loaded nose cone with the parameter changes input in the section areas below.

I will add the Save and Save As buttons if this is usable. Another button will be to resize a standard nose cone for another body tube size.
