Well I'm working on a model which is having almost 100 configurations. Though I'm able to generate the part using the design table, but rebuilding everyone and checking is like a trouble thing as the model contains a seep feature thats take too much time to rebuild. Also I had never used the macros. So if anyone can help me out by sending me a macro (if possible) which can regenerate/rebuild each configuratios so that I can save my time and use it some where esle or if some one can guide me how to make a macro for this work Your early reply will be very helpful to me. Thanks & Regards Deepak Gupta
