Thanks for responding quickly.

The curve does run roughly perpendicular to the lines as you show on in the first image.

I attached an image (render) I found that shows this. I also attached the blueprint. I could just tweak the curve until I like it, but I'm trying to learn how to tackle this type of problem.

One idea I had was to use the Isect command to intersect the lines at a plane at the cross section line to create some points there. Then snap to those points and align them to the right cross section in the the right viewport. Would that work? If I turn on points and just grab the line and shift it perpendicularly downward I think this may work.

Thanks,
Jeff
