Using Solidworks for Scenery Design in FS9

I'm pretty good with Solidworks and Afcad and would like to start building airports for FS9, without spending time on learning a new 3D program. My main concern is exporting from Solidworks to FS9... has anyone tried it?Solidworks can export:IGES (.igs, iges), ACIS (.sat), STEP AP203/214 (.step), VDAFS (.vda), Tiff (.tif), Universal 3D (.u3d), Microsoft XAML (.xaml), STL.(stl), VRML (.wrl), Parasolid text file (.x_t), Parasolid binary file (.x_:(, eDrawings (.eprt), Adobe (.pdf), 3D XML (.3dxml), Catia (.cgr), ProE (.prt), JPEG (.jpg), HCG (.hcg), HOOPS (.hsf)It seems .xml is the key format to end up with .bgl's. Is there any way to convert these file types to .xml or even to another 3D program to get to .xml?Any help is appreciated.
