Extract Normal from a Brep?

Hello all,

I have a collection of points directly on a polysurface (recognised as a brep in my definition) - is there any way to read of the normal of the surface at these points whilst having the polysurface defined only as a brep in my definition?

Many thanks in advance,

Jay

Solution that debreps them in to surfaces, figures out which surface the point is supposed to be on, then Evaluates the Surface for the Normal.

Not sure if it can be done without messing with the polysurface though, hmm..
