Hi,
I want to set a normal vector for a plane (surface - roof)
I have 3d buildings in 3DCityDB
I used transformer "Triangulator" and I calculated the area based on "TIN Surface" and it's OK, but I don't know how to set the normal on surface?

If you want the Normals to be on the Geometry/surfaces you can use the GeometryValidator with the Issues to Detect containing 'Missing Vertex Normals'. You must make sure that the input features are Surface features and not 3D Polygons.
Everything that comes out of the repaired/passed port should contain a normal in the Geometry. You can see it in the Geometry section in the Feature information window in the Data Inspector.
