Hi,

Is there anything in the SDK that looks like creating a perpendicular line?

Perpendicular to what? A bit more context is needed

I´d have a curve and a point, so i wanted create a line perpendicular to curve and point.

Hi @Luciano_Luiz_da_Silv,

You might look at functions such as ON_Curve::TangentAt, ON_Curve::CurvatureAt, ON_3dVector::IsPerpendicularTo, and RhinoGetPerpendicularCurvePlane.
