FMETriangleFan.isOriented()

A face with a donut area will not be oriented if the normal of any inner boundary has the same direction as the normal of the outer boundary. Meshes and composite surfaces will return False if they have two parts that share an edge and those two parts are not consistently oriented with respect to each other. If the surface is improperly noded, the behaviour of this function is undefined.

Return type:

bool

Returns:

Returns True if the surface is oriented, False otherwise.
