Hi again
When you try to import a solid model from a software to another is almost impossible to have all the features of that model. For example, when you will import from IGS format in CATIA, you will be able to read only primitive solids, b-splines but without surfaces (and I think you cannnot know also the topology of the solids).
I suppose that its the same problem in SW (as I remember, for the time beeing, its also a Dassault product).
Maybe somebody can give us a little bit more informations about that (fer@xnet.ro).

Fernando
