Michael, I'd like to ask you if it possible for you to make clone of object. I mean the dublicate of object but that is copy of original not the new object. Like "component" in Scketch up. For example when I work on my projects, weels with tires take a lot of PC resources. But if I had chance to make one weel and clone it not copy, it will allow to save as 3 times more resources. What do you think?
