converting a 3D helix to a 2D spiral

I'm trying to define a spiral geometry in 2D (actually 5 co-centric spirals) by converting five 3D helices. I have defined Helix1, Helix2.... Helix5 and in the Work Plane I have created a cross-section at z=0 and converted to solid. Then I've exported a geometry file and saved it in the .mphbin format.
In the same model I added Component 2, this time in 2D, and imported there the .mphbin file. I have a problem now with specifying the materials, each helix (spiral) is made of different material. I cannot select different domains, to me it looks like the geometry is not a solid surface but just the contour lines that distinguish various spirals. If anyone had a similar problem and could give me an advice on how to solve it, I would very much appreciate it.
Thank you!
