is it possible to compute the intersection-curve between a n
is it possible to compute the intersection-curve between a nurbsurface and a planars
how is it possible to compute the intersection-curve between a nurbsurface and a planarsurface?
or simply:
how is it possible to compute the intersection of nurbsurface and vector(0,0,1) from point(x,y,0)?
best regards

it is impossible using dd interface.
from mathematical point of view i'm not sure it is possible to compute intersection as nurbs curve in common case. however, you can implement getting this as polyline, intersecting set of lines, belonging to plane, with nurbs surface.
