Rectengular intersecion of two nurbs

Hey folks,

I would like to stretch one surface until it intersects another surface. The problem is that those planes have been cut so if I just try to stretch the surface it will follow the underlying control points which are wrong. The surface used to be a little round at the end so I cutted the round part of and now I have a gap between the cutted surface and another surface.

Is there a way to intersect those surfaces together with the condition that the angle of the surface doesn’t change? There should be just a rectangular intersection.

(surface1)…| (surface 2)
---------------- xxx|
…|

the “xxx” shows how I want the surfaces to be stretched from side view.
I hope you understand my probem.

Thanks in advance. I’ll appreciate every answer!

Hi Bummel - can you please post a Rhino file with the objects?

thanks,
