Measurement of the "Straightened" length of a path So, I'm having a bit of trouble with scaling. An object I'm making involves the use of a path to form a curved surface, but I need the resulting curve to be within about 1% of an exact length.



So, if I were to have, say, this curve here that I made for purposes of this question... is there an efficient way to tell how long the black part would be if you straightened it out to a perfect line?
In the Animation Nodes addon there is a node to do just that: Get Spline Length.

The example usage is what you need.
