association/union walls on floor

[cadrev]

I have a problem with revit architecture 2013 and it concerns the association of a wall to a floor.
I have been using revit for a while and sincerely I thought it was a trivial operation until today. I practically need to create a wall that at the base
has a high coating 50 cm and thick 2. the wall must rest on a 50 cm high floor as the entrance of this hypothetical house that I must
realize is at +50 altitude. I attach the file to avoid posting many images. In example 1 (see section) I echo the coating with a profile loaded as extrusion. as you will see the linear wall behaves well while the arched wall can manage it only by union! and not association! why?
in the second example I used an overlay wall but in this case the association does not even work with the linear wall. . .
I think it bothers the fact that flooring and coating have the same height or 50 cm. for this reason I created another exmepious
of wall overlapped but with covering of 60 cm of height. in this case, in fact, the linear wall is associated..quello with arc no, just like
in example 1. I tried them all... even acting on the basic offset but I didn't come to head... it works, in some cases, only union but not
manages to manage the association. . Can anyone enlighten me on the theme? I hope to have been understandable

Thank you very much

I do not understand why it is a problem that the wall and the floor are well connected with the tool "join" for curved walls for simple association for straight walls. As you have seen, to join a straight wall and a floor, the union works well without doing anything extra. to adhere a curved wall with the floor, the tools of "join geometry" is necessary. both things are valid methods that the software uses to put things together, but the end result in both cases is the same.
