Thanks Richard for your suggestion. I tried adjusting the render mode to Flat but it does not update anything. To check this I changed render mode to single line and triangulated and both of these options did show in the model.
However when adjusting any 3D shading option like Flat, Phong or Gouraud the result stays the same.
Is there a way to turn off the light source in the model, especially in results "Static output processor" window?
Thanks.
