I’ve had a macro for FreeCAD for a couple of years that simplifies creating nose cones using parameters entered in a dialog. For many hobbyists, Fusion 360 is a more popular platform. Here then is a port of the program designed to run as an add-in to Fusion 360.

Also, Wikipedia has a great entry on nose cone design. https://en.wikipedia.org/wiki/Nose_cone_design
Try it out and let me know how it works for you!
