How to check whether the curve is C1 class?
How to check whether the curve is C1 class or C2 class.
Example:
x = [1,2,3,4,5,6,7,8,9 ......1500]
y = [0.56, 1, 12, 41, 01. ....... 11, 0.11, 3, 23, 95]
This curve is C1 class "function" ?
Thank you very much.

Why is G3 continuity only achievable between two edges?
Why is G3 continuity only achievable between two edges?
For example, curve 1/2/3, 4/5/6, 7/8/9, 10/11/12 are all G3 continuous. The center surface is built with G3 constraint on edge 5/2. Since curve 1/2/3, 4/5/6 are G3 already, how come edge 8/11…
