Rhino to ANSYS workflow (export solids and rebar)

I am trying to export geometry to ANSYS for calculation, that has solid polysurface walls/slabs and rebal, that are currently set as lines. I export to STEP but lines are missing. What are possible solutions to transfer rebar data? I am not very familiar with ANSYS, I just have to prepare file and hand over to ANSYS specialist. Is giving volume to that lines the only way to export them& If so, should I cut them out of a slab?
