Walls to Slab connection

[angeloWZN2R]

Hi all,

I am working on the architectural model of a building. I would like to ask what is the best practice when modelling in Revit about the connection between the wall and the floor. 

Would it be best  for the walls to be attached top/base to the floor ?

Walls with constraints level to level and therefore cutting though the floor ? (this way the walls can be seen from the upper floor plan and in my opinion is a bit confusing)

wall with constraints level to level and Top Offset= -thickness of floor

I would like to know based on your professional experience.

regards,

Angelo

You should model the walls they way they are to be constructed.

Some examples (there are many):

Ground floor masonry walls can either go to the footing below the floor slab, or sit on a concrete slab that has a thickened edge footing.

Metal stud walls usually sit on the floor slab.

Concrete tilt up walls can go multiple stories with floors framing into them.

I would model it base on how you construct in real life. As for attachment to base and top, I wouldn't do it. When you draw a floor, Revit will always ask if you want to attach. If user pick yes, it will randomly attached to closest floor and often give you warning message. Often this will slow down your model to a crawl. I would only attach to top or base if the floor/roof/ceiling is sloped. Make sure it is manually done by the user and not allow Revit to automatically attached randomly.

If the wall is set to the underside of floor, then in the wall property you would set top offset to Level 2 minus the floor thickness.
