Mean Curve


(EA) #1

Is any option to make a Mean Curve?

something like this (the mean line):

TweenCurve is the obvious command to use - but the results depend on how the curves are parameterized.

A method for finding the mean curve which is the set of points which are equal distant from the two side curves:

  • Create set of circles which are tangent to both side curves. (Spacing of circles is not critical.)
  • Find center point of each circle
  • CurveThroughPt through center points. (Chord may give smoother result than Uniform.) Alternative would be InterpCrv.
