hello
In the package Geom you have a class Geom_BSplineCurve. You can use D1() method to compute the normal verctor of the curve at a given point. For more details have a look at Geom_BSplineCurve.cdl file.
Good luck

Calculate normal-vector of a BSPline_Curve
Hello forum,
does anyone know how to calculate the normal/tangent-vector of a BSpline-Curve ?
I have found something alike for BRepLProp but only for edges (TopoDS_Shapes).
Maybe this can be done with some tricky class-conversion ?
Any hint is really welcome !
