actually i want to rotate the whole assembly in catiaassembly work bench toolbar is it possiblle
Simply Use ctrl key( used for selecting many parts at the same time in CATIA) and Compass ,you will able to rotate assembly.
Gee you ask some crap questions!
Insert the assembly into another assembly and use multiple instances & constrain them, or use a skeleton with a pattern or use fast instantiation. Dead simple, unless i misunderstand you, which is quite likely as you're not very good at explaining what it is that you want CATIA to do.
Have you done even a tiny bit of training?
