musa@cs.arizona.edu (Musa J. Jafar) (11/14/90)

Hello there, I Know all the discussions Have been about LSI CAD
I am looking for current trends in CAD databases "Geometric CAD"
Any list of Current G. CAD sytems will be appreciated.
How do they implement, storage & retrieval.
I read a couple of articles by Kim, Katz,....
Any commercial systems??
Thanks.

How about a discussion about geometric aspects of a design,
How to store manipulate & Retreive?
How to maintain properties of a design?
How to propagate Properties?
