Hi,

I am facing an issue where wall was not rendered properly by the FME inspector as it has direction issue. I tried "SurfaceNormalExtractor" but I didn't get any information out of the transformer. Please find the screenshot. Could you please help me in this regard.

Hi @kumarkannan1980​,

Please try using the PlanarityFilter transformer to extract the surface normals. In the transformer properties, set Surface Normal Output - Expose Surface Normal to Yes.

For the top faces of the walls, check that _surfaceNormalZ is near to 1.0, and that the faces have Front appearances set.
