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.

If your holy grail is the ability of using infomation to drive drawings I have to ask if you have any idea what that could lead too?

- Design productivity would increase by factors of hundreds - perhaps thousands.

- Information would be infinitly adaptable.

- Structure that information properly and knowedge will result.

- We would begin to realize the full potential of computing power.

Is that what you were saying??

Do you want AutoCad to edit the drawings right out of the

database?  How

would you want to put them in/get them out, of the

database?

I think the more traditional problem is to extract information embedded (within blocks) in a drawing to produce a bill of material.  As long as the text is stored in a block it is a trivial task.  On the other hand, if the text is free floating in the drawing, finding it is a little more difficult but still possible using lisp or vba.

Auto cad has prebuilt tools to extract/link data from blocks to any ODBC compliant database.  Of course, the holy grail would be to eliminate auto cad altogether and then render drawings from the data stored in the database. :-)
