Looking at this further, it appears that cubes may have a smooth
shading problem due to the way the normals are calculated. If you
AutoGlyph the normals of a smooth shaded object, I'm not sure they
are right; however, this is a moot point since what you want is
faceted shading on these cubes anyway (normals are connection based
not positions based).

Hi,
I have reposted the problem but the answers did not solve the
problem. I have 4 cubes.
+-------+--------+-------+
| | B | |
| A +--------+ D |
| | C | |

The shading of B,C is erroneous. I included this simple exaple in an
import.dx file. Try
Import(file=import.dx)->ShowBoundary->AutoColor->Image. See bottom
and front view....
In a mush more complex flow field I have to diel with, looks very agly...
