Beginnerquestion: 2D lines in SOLIDWORKS importing to ANSYS component system
 

Hi, i've made a geometry sketch that is a duct (so 4 lines connected to each other)
In this sketch I also made some more lines so I can divide some regions into finer meshings.

But all I have is lines, no surfaces, or solids.

I want to analyse the flow through the duct with either FLUENT or CFX

(Before this i used gridgen/solidworks to make the geometry and then mesh it with gridgen and analys it with cobalt, but I cannot use these anymore. So now I miss the mesh/block making step I used to do with Gridgen. So i figured i'd just load it into either turbogrid or icem or mesh or whatever from ansys, but nothing can read the geometry from solidworks)

So my question is how can I import the lines from solidworks into another component of ansys and then start meshing etc.
