all those rectangles are actually windows, how to make them go along with the surface I designed?
thanks.
PS:
to be more clear, I uploaded the definition(in this case, I changed the rectangles to circles), what I finally want to achieve is to make several Attract-Points, the closer windows to the Attract-Point, the bigger the Radius....
I suppose you'll have to either get the Surface Normal vector at your window center points, or slice your surface at the window heights, then use the tangent vector of the contour curve. Perhaps you might even need both to accomplish the orientation you're after.
I'm guessing the windows are all in the XY plane now because you're using a Point to control the rectangle orientation instead of a Plane.
Surface Normal is an output of the Evaluate Surface component. You'll need to figure out which uv coordinate your individual windows are at first though. You can do this using a Surface Closest Point component.
