How-To: Export Visualize scene graph data to non-PRC file format

When you export Visualize data to non-PRC file format, you first export to PRC, then use Exchange to translate the file to the format of your choice.

try
{
	HPS::SprocketPath sprocket_path(GetCanvas(), GetCanvas().GetAttachedLayout(), GetCanvas().GetFrontView(), canv.GetFrontView().GetAttachedModel());
	HPS::Exchange::ExportNotifier notifier = HPS::Exchange::File::ExportPRC(sprocket_path.GetKeyPath());
	notifier.Wait();

	if (notifier.Status() == HPS::IOResult::Success)
	{
		HPS::Model Model = HPS::Factory::CreateModel();
		Exchange::CADModel modelFile = Exchange::Factory::CreateCADModel(Model, notifier.GetModelFile());

		HPS::Exchange::ExportOBJOptionsKit option = HPS::Exchange::ExportOBJOptionsKit::GetDefault();
		HPS::Exchange::File::ExportOBJ(modelFile, "output.obj", option);

	 }
}
catch (...)
{
}

Or you can export with HOOPS Exchange API instead of the Visualize-Exchange API.
In this case, A3DSDKIncludes.h needs to include, and initializing the library.

A3DSDKHOOPSExchangeLoader sHoopsExchangeLoader(HOOPS_EXCHANGE_BINARY_DIRECTORY);
if (sHoopsExchangeLoader.m_eSDKStatus == A3D_SUCCESS)
{
	sHoopsExchangeLoader.m_psModelFile = notifier.GetModelFile();
	A3DExport sExport("output_ex.obj");
	sHoopsExchangeLoader.Export(sExport);
