beam system - cutting intersections

[Stefano.bp]

good evening to all, I failed in the forum to find answer to my problem.
I write you first to ask for advice, and then to help my problem:
I am making the model of an old building that has a wooden cover, for the ornamentation of the beams and of the beams I used systems of structural beams, it seemed all ok (apart from some magheggiata for the positions).

Now I find myself having to combine/cut the beams and beams when they meet or when they count a wall...only that revit does not allow me.
If I select a wall, it doesn't make me select a beam, if I select a beam, it doesn't make me select another beam/wall for the union of geometries.
The question is what am I wrong?
and the advice I ask is: how do you manage the wooden roofs with beams, current beams and beams?
Thank you for any response! !
Say hi.
allego photo in which I highlighted some of the points where I would like to combine geometry

to no one came any idea...now that I finished the model I rode a little not to see the profiles of the beams that intersect the walls.. but I just do not want to join/cut between the geometries! !
What did I do wrong? ?

First, I want to evidenzure you that without the supports to the diagonals of the bonnets, the beams and the beams are not standing.
if the supporting walls of the primary beams, were really the drawn ones, the beams on the short side rested on the escalation of the long ones, can not have the attack on the "point", but possibly rested above.
for ulrimo, in the orditura drawn, lack the hooking strips of the tiles (or other) that must be orthogonally laid to the beams.
provided above, the perimeter wall must reach the lower level of the strips.
the errors that appear to you are probably due to:
- for the cutting of the walls, to the not perfect alignment between the slopes of the wooden structure and the "falda" of cover; Therefore I recommend you to draw the wooden structure, for single order, and applied to the cover mantle host (i.e. a fictitious roof host), using the command: select>new> surface, and select the roof surface (or ground).
- the attacks on the "balances" of beams (and strips) must be corrected by laying angle beams on the fittings of the bonnets and decreasing their length so that you do not create "the intersection" (as happens in the construction reality)
