Understanding interior walls in Revit Sample Project Snowden Towers

I'm studying the Snowden Towers Sample Project to get a good idea of best practices for modelling. 

I noticed that the interior walls are somehow constrained to the bottom of the floor above, and I cannot figure out why. Hoping someone could help me understand here. 

 

The wall is not attached to the floor above. And even when it is un-joined it still constrains. Even when I copy a wall and unconstrain it, it still automatically sits just below the floor above. 

What is going on here! I'm so curious now.

The wall's top IS attached to the floor above, otherwise the Detach button would be grayed out.  Click the Detach Top/Base button, then Detach All, then you can adjust the height of the wall (via Top Offset) manually.

Many of them are associated with a Global Parameter, expand the properties palette so you can see the Associate Parameter button on the right edge of the palette.

Ah, interesting. However I'm not seeing this associate parameter you speak of. I'm going to take a guess that this is a full Revit thing. I'm currently using LT.

If that is the case, this all makes sense now.

Once I click detach, the detach all option is greyed out. I think @SteveKStafford was correct. The wall is constrained to a global parameter, and I'm not seeing the associate parameter option because I'm in LT.

Aah, yes LT will make that hard. There are quite a few Global Parameters in the Architecture model, demonstrating their use.

@SteveKStafford Since I'm using LT, instead of relying on the Global Parameter (for the interior walls), I will make a Level for the bottom of structure for above floors. As a workaround.

I'd use Attach and select the floor above. Extra levels for anything other than primary vertical datum (floors/parapets etc) are not ideal. They create potential display issues in views, possible hosting mistakes, and additional view range complexity for the team.

Seems as good a place as any to ask for clarification in case it might help another:

 

Student here, working on a project for class.  I erred in attaching walls to ceiling on a project not realizing the future need for dropped ceilings for MEP etc. 

 

Detaching second floor walls was straightforward enough, but when I tried to do same on ground floor, the properties panel showed the "Top is Attached" box checked and greyed, and the "detach top/base" tool in and of itself did nothing.

I had to select "Detach All" on the contextual Options bar before I could return walls to their proper height.

 

I wonder if someone could direct me to a primer that discusses the nuances on attaching and detaching.  This did not seem intuitive to me, and I did not find a reason I had to do "all" on one set of walls and not the other.  I am sure I failed to do some "best practices" that necessitated this.

 

Thanks.
