Can you change the level for unattached walls so they don't loose their position in the model?

Hi,

So I'm in a pickle. I received a completed model to examine, and whole model has one huge mistake. Two different buildings are in a model, and levels are set according to only first building, while levels of second are not set (they differ in height as well as in number). The first building is ok, but everything in the second one was modeled according to the levels of the first one. This made all the walls of the second building having base constraint at the level they are not on with an offset, and top constraint is "unconnected" with an offset. Same thing will all other wall based families (doors, windows etc), floors and roofs. Everything is "unconnected" and in wrong level now. When I got the model I was instructed to add new levels and "adjust everything in the second building according to new levels", because all elements have to be in correct level for scheduling. I added new levels onto which I need to adjust all parameters. I tried copying and pasting to correct level, but then my model "floats" in according to the original offset (same with individual elements). So just changing the base/top constraint doesn't work. 

Is there a way to change the base level and add a new top level for walls without them changing the position in the model? When I do it by hand they attach to the level, but keep the original offset (the float in the air). 
Is there a way to change the base level of floors/roof/windows/doors so they retain the position in the model? Same thing as above happens when I do it by hand.

I REALLLLLLY don't want to do this by hand, because it is a complete overhaul of the 5 story building, which basically means drawing it from the scratch.

Thanks to all good people here!

I would suggest linking the file to a clean project created from scratch and using the Copy Monitor tool to copy levels and other building elements. You will likely still need to do some manual work to update the base and top constraints to the new levels in the Properties palette

As @vitorbortoncello smartly suggested. Linking is the way to go, however in your case, maybe it would be simpler to Group the 2nd Building Elements together, save the Group as a Link in the Project and then Bind the Link  with Levels checked.  Then Ungroup the Group created.

Hey,

It seems like you can do it in Dynamo. If I were you I would do this in this sequence:

1. Select all elements to be changed it' s parameters.
2. Select the levels to be assigned.
3. Find the elements' nearest levels and assign them

Thanks everyone, linking was not an option since both buildings have to be in the same project, I was thinking about using Dynamo, but I have found solution elsewhere. I used pyRevit's extension EF-Tools which allows you to select walls and change top and bottom constraints, so what would eventually be a tedious manual 4 day work (at least), it took me 20 minutes. So thanks again everyone
