Re: PostgreSQL and AutoCad

As I have a vested interest in storing AutoCad stuff in PostgreSQL, I
searched for something like this a while ago and I ran across this..
I haven't really had a chance to play with it yet

http://sourceforge.net/projects/dxf2postgis/

I'm personally interested in the idea of versioning for a drawing.
Instead of storing the entire drawing for each version, one could
theoretically just store the vector additions/changes/deletions that
happen from one revision to the next.
