    It might not make a SECOND wall, but i THINK youll find (and i may be wrong) that the wall post-offset has a different Element ID than the wall pre-offset. Meaning: Yes, its another (different) wall. Breaks copy monitor, breaks edit cut profiles, breaks associations. Otherwise it would be called Move.

    I was somewhat surprised just now to find that Offset with Copy not selected does indeed just move the wall. And does indeed not break Edit Profile. Didn't test anything else, but I can't imagine it wouldn't behave just like a move for all intents and purposes. Woot!

    FWIW, the process I posted is really only appropriate when you have a large complex project, you are laying out walls in SD and you KNOW that the wall system is going to change two or three times thru DD. We did it on a 600,000 SF, $500 Million project where the client was insisting on a stucco skin, and we really wanted them to consider other options. We won the day and had to fundamentally change the entire skin of the project on short notice. All the work up front really helped.

    Same Element ID and everything? Interesting! I didnt think it ever used to be that way! (BTW- i was saying Edit Cut Profile, not Profile... Copying a wall (or creating a new one, mirroring, etc, wont carry it over).

    Yep, same EID. I was surprised. And I didn't test cut profiles, just edited profiles. But I was assuming behavior would be the same. I just checked, and Cur Profiles work as desired too!

    Interesting. So they can make OFFSET work correctly, but they cant get MIRROR to do the same thing? Figures.

    I can kind of see why MIRROR wouldn't work. Offset you are just moving the wall in a way and mirror you are flipping the orrientation of everthing and moving it, I could see how Revit would get that confused.

    I dont know. Flip controls dont replace an object, but mirror does. Both flip an object around. Its inconsistant, at best. I wouldve sworn i tested them ALL once, and they ALL created new EID's. It was the basis for how i came to tell classes you always modify, you never delete and replace. I guess there is a chance i tried every single one of them.... Besides offset, LOL.

    Some very interesting information here! Thanks everyone.

    The project where this issue emerged the first time, was a 100.000 SF (Foot print - but probably tiny compared to Gordons) project, with lots and lots of corners, and probably 100´s of exterior walls of different types.

    It was nearly impossible to pick a chain of walls, due to the complexity of the project, and offsetting each single wall was not really an option. (I´m lazy)

    Gordon ! I love the worksettet solution And will probably steal that idea when a project like that come a long the next time. (If ever)

    Besides, it´s nice to know how the EID´s act with each command - Never realized that !
