HELP PLEASE!- controlpoint moving along rotated profile

hey!
im sorry but i need some help. i added a picture to make it easier to understand.
i got some profiles (they are all different, with different numbers of controlpoints) and some splines (with about 20 control points) at one point of the profile-pline the splines are connected to the splines.
now when i rotate the profile the controlpoints of the spline should be moved to the profiles controlpoints. im not quite sure how to do this- and just got about 2-3 days to solve my little problem.
hope the time will come when grasshopper s goin to enrich my work - not slow it down ;D im just joking, its just a lack of knowledge

thx michael
