Offset Curve and tree structure

Hie,

I have 15 curves in two branchs, two distances and two surfaces. I am trying to create an offset of ever curve, the curves of the first branch in the first surfaces and the curves of the second branch with the secon surfaces. I get to make the offset in one direction but not in two…Could you help me?

Regards.
