Dear Tim,

I guess Elaine also saw the performance of the new STL file developed by
Armonicos, a
Japanese software house, at last Autofact.
The STL data created by this new STL format has the topology of each triangles,
so the
fault of the data is drastically decreased.
Armonicos said they can release the English version by next February.
You can see some of their products in their homepage,
