Thanks Ilan this looks promising.

  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.

    - 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. :-)
