3d set projects & docs

[Thomas Andrews]

Hi Everyone,

I would like to know if there are any open-source SET projects currently
running, and also if there is a document repository for 3D SET. If not
I, would appreciate anyone being able to point me at any reasonable
source of info about 3D SET, as I've not been able to find anything so
far. What I'm particularly interested in is the differences between 1.0
and 3D.

Many thanks,
Thomas
