Currently I am trying to find the intersection of splines(Control pt, knot, spline pt) with planes (origin, normal).

As context: I have traced elliptical splines around areas of interest of a 3D image (.stl) and would like to extract the points on the spline that intersect with planes defined from other landmarks on the 3D image. Eventually, I would like to digitize the long-axis of the 3D surfaces bounded by each splines with a number (e.g. 10) points along the surface.

Unfortunately, I am not too familiar with the spline toolbox. Any help direction on the appropriate functions and methods would be much appreciated.

Thanks.
