Create a frame at a specified distance along a curve. The resulting frame will have its Z axis along the curve tangent, its X axis along the curve normal, and its Y axis along the curve binormal.
Distance along the curve to create the frame. If this value is outside of the range from zero to the length of Curve, the point will be extrapolated. The extrapolation will be linear for Lines and Splines, and circular for Arcs. If Curve is a Polycurve, the extrapolation will be based on the type of the segment at the corresponding endpoint.
