How to construct line from one curve to other which is perpendicular to starting point? I have curve1 and curve2 and known point on curve1 from which need to draw perpendicular line to this point from curve2.
ProjectPointOnPerpendicular1 method doesn't give expected result as it draws perpendicular from curve2 not curve1.
ptEndPoint = oBsplineCurveElt2.ProjectPointOnPerpendicular1(ptStartPoint, ptBiasPoint, Matrix3dIdentity)
