I would personally model the walls full height for exactly the reasons you give, then Join Geometry cleans up the floor to wall connection. Revit hates having more items than needed. I'll do interior walls explicit height but shafts, elevators, stairs and exterior walls on tall buildings as full height.

Exterior walls, shaft walls, etc, modeled full height, here, too. If you model those level by level you will hate yourself later.

Wouldn't it be cool for walls to have a parameter like stairs that says "repeat from level x to level y". Draw one wall on level one, and it would automatically repeat up to the other levels, and a change on any level would update the repeat...wishlist anyone?

Isn´t that already covered by using groups or links in multiple stories?

Start with a highrise tower in Revit with the exterior walls running all the way through. Work the whole week on the glazing configuration and the mullion patterns and then on the following Monday your Project Architect wants to see a few balconies on the 5th to 10th floor, the penthouses change on the top floor, oh and by the way the engineer suggested we change the column grid for the south end of the tower so we have to start stepping the floors from 12th up.

Now you have a month to document your first precheck set.

Get back to me if you still think that going with full height walls is better?
Shaft (stairs - elevators) are the only ones that might be concidered. But here the shaft opening tool works its magic.

First thing I ever learned and will never forget in Revit. Saves me thousands of hours with my user on every project.
Model it as they will build it. Dont fake it and dont ignore the building science.

Cheers.

I would absolutely still do the skin fuill height, and i bet those changes would be done faster that way too.

For stairs and such, i use groups to keep the walls in the same location in plan, unless the field guys are actually running the walls past the slab edge.
