OK. fair enough.

I agree with your priority ordering.

I have not yet presented them, no, but that is partly because they
only look good from directly above.


BTW on a related matter I tried to export a model to vrml and 3dmf and
found that I could not find anything that actually worked. The mview
viewer segfaulted, the openvrml viewer didn't seem to be suitable for
an object (as opposed to a world). I couldn't build the viewer for 3dmf.

I will trya bit harder and report more if I really can't get it to go.
