Trouble exporting to dwg and dxf

[mcfetrmatt]

Hi there,

 

Im trying to export my rhino model to dwg or dxf so I can work on it in Revit, although solids don't export? I select everything (21 curves and 125 polysurfaces) and export to dwg (setting is set to default), afterwards rhino then tells me that 125 entities were skipped. And when I import this into Revit only the curves import..

 

Any ideas? I dont remember ever having this issue. Do I need to convert the polysurfaces to meshes first? if so how?

 

Thanks for any advice
