As I recall, 'AddSplineThroughPoints' (which has disappeared along with WizoScript) took the degree of the spline as an argument. Typically that would be 3 which gives the usual cubic spline, but alternatively 2 for a fit using 2nd degree polynomials. (I never tried 1, but it would be interesting to see the result. Maybe just a polyline.) Does anyone know if that can be resurrected, or duplicated somehow?
