Offset curve based on surface normals

I have a curve that is defined as the intersection of a surface and a plane. Additionally, I have an offset of the surface.

I would like to get the corresponding curve on the offset surface - essentially, a curve that is offset from itself using the normals for the surface at any given point.

Can anyone recommend how to do this?

Since nobody responded, I did my best to approximate a solution.

I divided the curve-on-surface into an arbitrary number of points, and then used the evaluate surface component to retrieve the surface normal at each point.

I then drew a line from each point to the offset surface, using the corresponding surface normal for direction. I then interpolated a line through the intersection points of the second surface.

I'd like to think that there's a cleaner and more accurate way to do this, however.
