Making Arc but they are not horizontal

[Pierre.Houde.Mclean]

I have been trying to make curves so that I could transform them to Rebar. Been able to make horizontal one at the same level. Bu now I have to make them follow th slop. It seem that it is the vectors but not sure, can someone have an idea?

Try making a plane and use Curve.PullOntoPlane maybe?

Thanks, just tried another thing. I realized that I did not put the center of those circle at the right Z elevation, darn. so now I almost have a sucess. I just need to figure how to put the rest of the bars that are missing in other elevations
