I was recently assigned a CATIA project in which we have to make "something engineering-based." So I chose the International Space Station. I'm not looking for it to be perfect, but I want to put some effort in this and make it look good. My problem is finding some good specs. I found some general specs on this site http://www.spaceflight.esa.int/users/downloads/factsheets/fs001_12_iss.pdf but it isn't enough. Any ideas on where I could find some of the finer details? thanks
