Is it possible to convert a surface to 3d pts, lines or polygons
background: I've been given a surface from Civil3D and wrote it to an esri filegdb multipatch feature class using workbench, however you cannot use a multipatch with the surface tools in esri (contour, difference etc.) so i am attempting to recreate the autocad surface as an esri TIN. we don't have access to the masspoints or breaklines that originally generated the civil3d surface

Hi @nfink,
To be able to get hands on 3D geometry in FME you need to convert the fme_geometry to something that FME can deal with internally. I assume that you've got an IFMEMesh geometry type that conflicts with several transformers. What you've got to do is coercing your mesh to 3D Polygons. To do so
Keep in mint that this approach will only work for geometry but not for texture! You can't keep texture information during coercing to polygons.
Hi @nfink, if the surface geometry is an IFMECompositeSurface, the GeometryPartExtracter with this Geometry XQuery can be used to extract 3D polygons from the surface.
