PROBLEM
When using the Layer To KML tool to convert extruded features in ArcScene to a KML service with 3D extruded features in Google Earth, the 3D extrusions do not appear.
This problem occurs if the polygons are in a geographic coordinate system (GCS) instead of a projected coordinate system (PCS). The polygons must be converted to a PCS before using the Layer To KML tool.
