Wall and Slab Intersection in Section

Anonymous
Not applicable
How can I make a Wall and a Slab intersect properly in section?

I made a compposite wall and a composite slab with the same priorities and fills and I have "Enable Skin Priorities" switched on.

In the section window they intersect proprly only when the Slab touches the Wall. When the Slab touches the inner Composite's line they do not intersect at all!

What I am writing here is not a solution, but rather a wish.
If we could have Profiles assigned to Slab edges that would solve this issue.
Just a you can have a Profiles Wall, we could define a Profile and place it along one of more edges of a Slab. So the edge of the Slab would be a Profile and this Profile would extend into the External Wall.
Then no SEOs would be needed because we could model the whole thing with Profiled Walls and Profiled Slab edges.
Let's keep wishing.

Finally made it with Complex Profile Beams.

Took me half a day model and adjust all the Beams!

What a waste of time!

If you are going to use Beams have a look at this post:

I already spent 2 hours of making complex profles with different mateials! Several hours more to go!

Well the only solution I've come up with this issue is to use one slab for the concrete slab and a composite slab for the floor coating.
So you model it the way you built it:
A single concrete slab for the total floor (unless you have different levels) and composite slabs (magic wand-them) in each room.
This is works better IMHO since you don't have the same floor finishes in each room (bedroom , kitchen, bathroom etc) and you can keep the structural part (concrete) separate from the finishes and change the flooring of one room seperately without changing the entire floor slab.
As for the exterior veneer you can use a composite wall and subtract only the concrete slab.

I use same approach but instead of a second slab for the floor finish on top of structural slab I use Interiors wizards Floor Accessory because it links to the zone and its size follows the zone perimeter(even a windows and doors recesses!) and they can be updated with press of a one button when linked zones change. Though it is not so convenient to set up as composite slab. Also you can't use eyedropper and syringe to adopt its settings because it will also store the shape of a floor accessory element, so you have to use favorites to store the settings.

Petros and Sinatropus, these are very nice ideas and I will definitely try them both! Now I model a separate slab for balconies and terraces (because of different flor thickneses), so the amount of work remains the same!
