SketchUp to Cura - Filling Rooms with InFill

[cheveldi 0]

I drew a School Basket Ball Arena in Sketch and am printing it through Cura.  It is filling in the rooms.  I want it to fill the walls so I can't eliminate infill.  How do I get it to not fill the rooms in?

Sketchup is very good in making bad models. Check the model in x-ray mode in Cura. If there are red areas, there are faults in the model.

I also use Solid Inspector plugin for Sketchup to make sure I valid solids and no holes in the meshes.
