How to join different objects (different modifiers) What I would like to do is a merge of two objects without applying their own and distinct modifiers. 

In other words: the first object has Sub.Surface modifier active but not applied, the second one does not have any modifier. Can I somehow join them without losing the sub.surface of the first object and avoiding the second object getting that modifier as well? (I wouldn't like to apply sub.surface before joining them)

Thanks
You can set the joined mesh CREASE where you wish to limit the subsurf effect:



with CREASE 1.0 subsurf has no effect at all...
