Thanks for the reply. (Unfortunately) it confirms what Peter Cracknell
wrote, while making it even more understandable. Just a few thoughts
of my own:

True. But Megapov *can* do CSGs using either the mesh or the mesh2
format.So, couldn't (and pardon me if I put my foot in my mouth through
ignorance) Moray export the *results* as a solid mesh (mesh/mesh2 with
'inside_vector ' enabled). I believe Peak3d does something similar.
Would this mean a major reworking? And wouldn't it be worth it, combining
the
power of both sPatch/ Hamapatch (especially now that you *can* do
lofts/skinning in HamaPatch using the AMexport/AMLoft utility?

Which brings me back to my second pt: Would there be a utility  which would
allow me to export to sPatch so that I can use the power of both. I really
would love to use Moray for my normal (architectural) work but it's lack of
spline support (& vertex editing) are discouraging. Otherwise, in many
ways, it is a truly wonderful program; especially int it's Pov-Ray
interface and handling of CSGs.

Sorry for rambling. And thanks again, both of you, for your clarifications.
