I have a parent assembly in which i added a sub assembly.I then set the sub assembly to flexible and then i gave a few mates. Then i used component driven patten to get tthe instances of the sub assembly that i introduced. When i change the parameters in the parent assembly , due to mates it is being reflected in the first sub assembly that i introduced but am not able to get it on the instances created by using the component driven pattern.
Make sure that components in the pattern are also set to flexible. Also simply edit the pattern feature and click OK (this might do the rebuild)
