IGES type 402

I've succesfully read various IGES files, but I'm having problems with group entities (type 402).

The IGES.PDF file says that such kind of entities can be converted by the mean of:
IGESGeom_Group ..._CurveAndSurface
..._GroupWithoutBackP ..._CurveAndSurface
..._SingleParent ..._TopoSurface
..._SingularSubfigure ..._CurveAndSurface

..but I can't find these classes..?!?

Is there something new and undocumented about this topic?

Hi Fabio,

If you read carefully, correct name should start with IGESBasic_ for group entities.
