I tried to extrude walls in FME from chopped lines (2 vertices). I am using ground height to extrude. The middle portion of the lines for the building slope roof is not extruding correctly.

  • Please provide more info. What data was your original file in? Which fme function did you use. – johanvdw Dec 6 '13 at 14:28

I suggest you create a buffer with a negative value using the thickness of the wall as a reference, then you extrude the polygons resulting from the buffering.
