Is this a self-supporting truss? I was thinking of removing 4 meters of the "heart wall." The roof slope is 23 degrees and the facade width is 11 meters. The depth is also 11 meters. In any case, I will place a glulam beam in the attic to reinforce the roof. The question is whether I need a "thick" beam or if a "thin" beam is sufficient depending on whether it is a load-bearing wall I am removing. If they are self-supporting trusses, I would probably place a "thin" beam in the attic in case any of the trusses sink down a centimeter when the wall (support) disappears. Grateful for any answers!
Attaching two more pictures, one with the wall I plan to remove and one with where the LTbalken (in the attic) should be. The attic is not habitable considering the roof slope.

I think it looks like the wall carries the potential wind and not the roof.
Load-bearing walls look like that, going up to the bottom chord of the truss, near its middle.
But it does not make it obvious that it is a load-bearing wall in this case.
It may well be true, but that the wall should carry the roof I don't see due to how a truss takes up forces.
However, the wall can carry the attic floor.
Furthermore, an LT bearing should suffice nicely, run the beam in the lumber industry's dim-program.
However, you should be completely comfortable with what you're doing; otherwise, I recommend hiring a structural engineer.
I calculated my trusses (FEM). However, with the difference of 7.5 m long and 26 degrees. The maximum tensile stress occurred at the top of the beam resting on the "heart wall." With the same calculation without the "h-wall", the maximum tensile stress decreased slightly, which then occurred at the bottom of the beam instead. My trusses were thus self-supporting, and a support in the middle slightly worsened the situation. But with new unloading at the same place as the current wall, the present load condition is mimicked, which without calculations must be best. It also results in less ceiling deflection.
Attaching two more pictures, one with the wall I intend to remove and one with where the LT beam (in the attic) will be located. The attic is not habitable due to the roof slope.

It should work well... with stable hangers from the trusses in the LT and having the LT stand on double studs or LT pillars, it will be good....
It is not load-bearing for the rafters; however, it is likely there to reduce the deflection in the ceiling. That is, you should transfer the load, and the way you have drawn it works well as long as you properly anchor the underlying floor joists.
Villa vista, I have tried that program but I can't find any construction that resembles mine. Which one should I choose? 1.5 stories? That doesn't really match considering that the attic isn't "expandable". I would have wanted an option that is 1 story.
