Hello, I'am having the same kind of question, currently doing multiple FBX exports by hand from NW models. Jutters, you said : >>Following JavaScript function within the Model JavaScript class should provide what you need: >>bool ExportFBXModel (const QString &fileName, const QVector< int > &classIDs, FdoGeometry *boundary, const QString &targetCSwkt, Vec3d *offset=NULL) Can you give me some more information about the way to access this Javascript function ? Is it necessary to use the ActiveX control into a HTML page, to enable it ? thanks a lot in advance, it could be a great time-saver for us ! Regards,
