Thanks George,

I always seem to come back to your excellent work and regularly dazzle
visitors with your structures. Thanks for the advice, I may have a go
at replicating the tangled reindeer into a structure for a test part.

Keep on inspiring

I've tried quite a few, and my experience is that no commercial software

is very robust when given complex Boolean operations. If you take the
union of a few hundred small objects, the package is likely to give an
error message or crash. If anyone can recommend a software tool (free
or commercial) that they feel is particularly good at complex Boolean
operations, please let us know.

Some of these files are like open-cell foam structures. I generate them

by different algorithms, not involving Boolean operations:
