This is task is for a node that calculates the lengths of splines.

Details

• The main complexity is that each spline has its own length, and the curve may have multiple splines.
• Therefore there are two output modes.
  • The first (and default) outputs the total length of all of the splines as a float.
  • The second creates a float attribute on the spline domain and fills it with the values for each spline.

Further Questions

• The name "Calculate Curve Length" might be better (more clear), but it is longer.

Implementation

Implementation is trivial, this can use the Spline::length() function.
