I am trying to devise a means of producing a helical coil with a smooth blend in the path between different pitches. I have looked at previous resolutions on this forum but sadly they produce what I would describe as a hinged connection between different pitch helical coils. Please see screenshot attached.
So can anyone help me please create a variable pitched helical coil arrangement that has a true blended path and not a 'hinged' path?
I have tried using the equation curve but do not have the expertise to write the necessary equation.
Any assistance would be most appreciated.
