here I have some requirement to extend the BSpline and NURBS surface
I use help function to check the Part.BSplineCurve and Part.BSplineSurface
but I can't find extend function in these two classes
in OpenCASCADE src/GeomLib/GeomLib.h
there is a function GeomLib::ExtendCurveToPoint, but I can't find it in FreeCAD
can anybody help me?
