having scoured the SDK for ages (probably not long enough - i'm weak willed) i cannot find the equivalent to the in Rhino command OnCurveOrient.
i have a grasshopper flow that essentially does the same thing, but a quick VB component replicating its action would save a myriad wires and components (i'm not keen on clusters as they seem to behave a little erratically) any pointers? T.I.A.
