I read a shp file, and work with the Extruder transformer , after that write to a geojson file, but geojson's geometry type is "MultiLineString", I want to set the geometry type of "MultiPloygon", how to set?
Solved
How to write a geojson file with a geometry type of "MultiPloygon" ?

Hi @keplerleee, you may have to transform the extrusion (IFMEExtrusion) to a multi-part polygon (IFMEMultiArea). If the base face for the extrusion was a polygon (not donut), a possible way is:
- GeometryCoercer: Transform the extrusion to a composite surface.
- GeometryCoercer: Transform the composite surface to a multi-part polygon (each face to polygon).
