Hello,
 I am working on the Pyramid type. If I have well understood,
a Pyramid is a baseLattice of dimension 1, with a set of layers 
describing the connections. All right.

My question is :
Is there a way to associate data not to vertices ( like this is done
in the 1-D baseLattice ), but to higher level objects ? ( e.g.
associate data to segments or faces...).
Wouldn't it be possible by using the nexLattice field of
cxPyramidLayer structure ?

Has anybody ever done this ?

Thanks in advance,

This is exactly what the nextLattice field is for. The elements of the 
cxConnection refer to the respective index into the nextLattice. This
way you can assign data values to edges, faces, and volumes.

Or if you use the pyramid for atoms, you can assign values to the 
different constituent parts. You might try looking (PrintPyr) at
the pyramid input to AtomicSurf.
