Entity definition

The IfcTextureCoordinateIndices provide the texture coordinates for an IfcIndexedPolygonalFace. The TexCoordIndex holds a list of indices pointing into the IfcTextureVertexList for texture coordinates that correspond to the TexCoordsOf.CoordIndex holding a list of indices pointing into the IfcCartesianPointList3D for vertex coordinates.
