Attached is a program (NX9) for creating sphere sheet solid cap. My reason for looking at this is when one creates a fitted surface for a sphere one can not directly get a cap. One needs to create the closed sphere and then trim the sphere to get the cap.
The program has been compiled for NX9 and is signed.
The zip file contains the a dialog file and a pdf with a basic outline and the dll which works for NX9.
