I have a shapefile with roof shapes. Now I will convert them into faces. This works well for almost all. But some areas are not planar. So theses non planar areas I fixed in a step before with GeometryValidator and then I will use FaceReplacer. But now the same issue was found "Non-Planar Surfaces". I thought with Geometry Validator these areas are fixed? Can someone help me?
Solved
FaceReplacer does not work with non planar surfaces which I fixed with GeometryValidator

Unfortunately this does not work either. Same mistake like before. FaceReplayer says "INVALID_GEOMETRY_TYPE"
My Shapefile is a 3D polygon with z values and stored as shapefile.
You will find it in the appendix!
A non-planar polygon will be a MultiArea after repairing with GeometryValidator, so you will have to insert the Deaggregator between GeometryValidator (Repaired port) and FaceReplacer.

Hi @limo , have you set Yes to the Also Check Areas parameter? The GeometryValidator won't detect non-planar areas, if the parameter is set to No (default).
"Also Check Areas - If set to No, this check will output all areas through the Passed port. If set to Yes, this check will determine an area’s output port based on its planarity." -- GeometryValidator Help

Hi @Takashi Iijima , yes I set Yes to the Check Areas parameter! The transformer fixed 4 Objects. However the face replacer says " Invalid Geometry Typ
These 4 Objects are roof shapes:
I will do Faces out of this polygons. So how can I convert them into faces?

The roof geometry could be a MultiArea, which cannot be transformed into surface directly with FaceReplacer.
Try using GeometryRefiner which transforms MultiArea consisting of a single part area.
If the roof polygon was a MultiArea consisting of two or more parts, try this procedure:
Counter: add sequential number as temporary ID to the roof polygon,
Deaggregator: decompose them into single areas,
FaceReplacer: replace them with Faces,
Aggregator (Group By ID): aggregate them into MultiSurface.

Yes it works now 🙂
So it is sufficient to deaggregate only repaired polygons by the geometry validator. I was not sure about this!
All 3D polygons can be converted into faces. Thanks @Takashi Iijima
