Derived logical volumes in VGM

Hi,

I want to replace our hard coded Geant4 based geometry with VGM. As a first step I wanted to import the the top level "world" G4VPhysicalVolume created with the existing geometry to VGM and then export to XML. I do this like:

void dump_geometry(G4VPhysicalVolume* world) {

    Geant4GM::Factory g4Factory;
    g4Factory.Import(world);

    XmlVGM::GDMLExporter xmlExporter2(&g4Factory);     xmlExporter2.GenerateXMLGeometry();
}

However, I get this error:

    Geant4GM::Factory::ImportSolid:
    Unsupported solid type (solid 'Module_1_OneModule_TestPMT_8inch_oil_body_solid") *** Error: Aborting execution ***

The solid in question is implemented in a class that ultimately derives from G4LogicalVolume. I'm guessing that the fact that this class is not a known, proper Geant4 class is causing the problem. Is this correct? If not, can anyone give a suggestion on how to track down the source of this error or at least to have VGM ignore tany unknown solids?

Thanks,
