Dear Bill,

Thanks for your quick reply. I have not tried building the example, but I am sure that it would display the same picture. Could you please point me to the correct ordering of faces?

Greetings,
Peter

The wireframe is displayed corretly. The cell consists of seven polygonal faces. I have made sure that the surface is water tight and that every edge is used exactly twice. I have also inverted the orientation of the polygons but that did not improve the situation.
