I could find some discussion about this topic in grasshopper component like this page
However, I could not find any information about rhinoscriptsyntax. Does anyone know which api I can use in rhinoscriptsyntax?
You might have a look in the Help for the rhinoscriptsyntax Curve module. There you will find things such as rs.CurveNormal(crv_id,t)
, rs.CurveFrame(crv_id,t)
, rs.CurvePerpFrame(crv_id,t)
etc. which might help you find perpendicular directions at a given curve parameter t
.

The CurvePerpFrame method works really well too.
import rhinoscriptsyntax as rs
crv = rs.GetCurveObject("Select a curve")
if crv:
plane = rs.CurvePerpFrame(crv[0], crv[4])
rs.AddPlaneSurface( plane, 1, 1 )
