## B-spline Approximation (CAD - Curves - S BSpline < Points ...)

B-spline curve going trough input points with definition of the way-in and way-out-direction. The first and the second point define the way-in-direction. The second last and the last point define the way-out-direction. The curve goes through point-1, point-3, the following points, but not through the second last point. Functions: UT3D_bspl_l2appr
