    I am wondering. How can I get normal vector of a curve in Grasshopper?

  • rezae

    There is not such thing as Curve normal but you can calculate perpendicular vector to certain point by rotating tangent vector of certain position on curve.
    I’ve attached a file that might help you

      True. Thanks for the prompt reply. Its just because I found one node in Dynamo i.e. “Cure.Normal at Parameter” and then I started looking the same node in Grasshopper. Thanks. Nice explanation
