Converting Contour Curves in Rhino to Archicad Floor Slabs

[weofwekfsjvbasdfivbj]

Hi, I have a series of contour curves in rhino which I want to convert to individual floor slabs in Archicad as pictued below. However, when trying to use the Archicad-Grasshopper Live connection, I get an error saying that the curves have to be on the horizontal axis. Are there any other methods in transferring these to Archicad?

You mean they have to be situated in a horizontal plane?

Can you check in Grasshopper whether they are indeed in horizontal planes?

And if not, modify them or project them onto horizontal planes and then use the resulting curves as the basis of geometry for the Slabs?

They are all individually horizontal, but they are not located on the horizontal plane (the XY plane)

And if not, modify them or project them onto horizontal planes and then use the resulting curves as the basis of geometry for the Slabs?

 How would I go about doing this?

I do not know Rhino and Grasshopper that well but I guess you could rotate them in 3D so they will be situated in a horizontal plane, or project each of them onto a horizontal plane.
