Well...whenever you have an error like that, the first thing you want to do is see what object is giving you the error.  So click the "Show" button and find the wall that's giving you problems.  There are usually alot of join errors and other problems when changing Level heights on a project that is far along.  Its  hard to say exactly what causes the error you're getting without knowing what your wall is, what its made up of, if there are any sweeps or anything like that in the wall, etc.

I realize this is an old thread, but has anyone learned a "best practice" for changing level heights late in a model? Most of the jobs we work on involve the architects changing the level heights by anywhere from a fraction of an inch to several feet after 99% of the building is modeled. I always get a million errors trying to raise or lower a level after there's any significant modeling done. Is there any way to do this without disjoining everything, deleting elelments, unconstraining elements, and all the other stuff Revit Structure 2012 wants to do when I try to edit a level height? I have one project where I need to raise the high roof 1/2" and another where I need to A) drop the 2nd floor 2'-0", and B) drop the high roof 4'-0". Any help would be greatly appreciated.

We typically have no problems. 

We will go to a section or elevation view and dimension level to level.  We lock all dimensions except the level dimension we want to change, then click on the level above if this dimension is to be increase and this unlocked dimension is then available for editing.  (Level below for a reduced dimension.)

I'll have to try that on the 2nd model. I've already typed in a revised level elevation in a section view and gone through redoing stuff throughout the model on the first model I had to revise. One other thing Revit did was "unissue" revisions to the level that I moved up 1/2". It looks like nothing was lost, and all I had to do was recheck the Issued control in the Revisions dialog box. Modeled connections don't seem to move up with a change in level, nor do any 2D objects in the sections. I'm assuming you still have to move your 2D stuff like annotations and detail components manually, correct?

Model elements associated with the level or dimensioned and locked from it will move.  You are right, 2D elements in elevations or sections will not move unless the are aligned and locked to model elements.  <<< Something I don't recommend because excessive locks will cause havoc with your model.
