Is there a possibility to convert an esri shapefile (geometry: polygon) to esri shapefile (geometry: multipatch) ?

If I try this directly Reader Esri shapefile --> Write Esri shapefile (geometry: Multipatch) I have no geometry only the attributes.

 

Does anyone know how to convert to multipatch?

Aha ok then I think you'll need to add a FaceReplacer

Yes @owen​ thanks for your hint. With face replacer I can convert it into multipatch. But I must also use GeometryValidator. Because sometime polygons are not planar. And this doesnt work for FaceReplayer. Afterwards I can aggregate these objects focused on GMLID by using aggregator. As a result I have one multipatch for each building!
