To join Automatically floor and walls

[TomasoCardia]

Hi all, How can I do to join all the walls with all the floors automatically (without to go to all single wall and "join" with his floor) ? in the picture are the structure part of the wall that is not joint with the structure part of the floor. 

Thank you!

No. And it's not just a Join. It's a negative height offset from level as well.

So to obtain this (subtract floor finishing), I have to do manually always ?

...another approach would be to modify the structural layer of the wall to have a negative base offset on placement. It won't automatically join to the floor's structural layer, but it will contact the structural layer of the floor.

You don't need to manually cut the floor. but you need to Attached wall base to the floor, or manually Join Geometry.  Wall core will extend to meet Floor core; Wall finishes will stop at Floor Finish.

DUH. Attach to BASE.  My senior moment for the day -- at least I hope it's the only one.  

Kudos @ToanDN

Its a bug. 
The way i fixed it is by detaching the walls from the floor, moving the floor to a different level then moving it back to the original level, then attach the wall again.
