I am writing C# code in grasshopper.
I have the following line of code:
Plane[] frames = curve.GetPerpendicularFrames(new double[]{0,1.0});
I would expect this to put a frame at the beginning and end of the line. Instead, it puts a frame at the beginning and another 1mm down the line. How do I get relative position instead of absolute position for GetPerpendicularFrames?
