Dear Sir!
I open the step and iges file.
The file is assmembly data.
Then I seleted the some face.
And I gained the normal of face.
but Normal vector itself is based on local axis.
But I would liked to gain face normal of world axis.
So i have to change local axis to world axis. How do i can ?
Help me..

I think that you extracted stored geom_surface from topods_face.
Extract tranformed geom_surface and use 'GeomLProp_SLProps(Geom_Surface)' or Directly use 'BRepLProp_SLProps (BRepAdaptor_Surface) '
