Hi US, I suspect the OrientOnCrv command uses curve rail frames to orient the geometry. You can get those frames in Grasshopper using the CurvePerpFrame component. In the Rhino SDK, the function that returns these is called RhUtil.RhinoGet1RailFrames()
This is not a very straightforward function to use, since it's designed to get multiple matching frames, rather than a single frame, like Rhino.CurvePerpFrame() in RhinoScript and you have to make sure you always supply the same starting conditions. -- David Rutten Robert McNeel & Associates On Nov 13, 12:25 pm, "[EMAIL PROTECTED]" <[EMAIL PROTECTED]> wrote: > 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.
