  The inside parts (Part 2 and 3) share an edge. The Parasolid kernel (the underlying 3D engine which drives Onshape, NX, Solidworks, etc) can't do a Boolean with things that intersect at an edge. You might be able to Boolean add Part 2 to Part 1 in one feature, and then in another Boolean feature, add Part 3 to the result of the first Boolean.
  
  Part 3 and Part 1 also look like they are intended to share a surface, but in fact have a weird gap/overlap situation.
  
  Overall, I really wonder why the sketch for the revolved shapes are created with so many line segments. It seems like something which would be better with a spline or some arcs. You're also creating things that could just be revolves with a sweep in one case and a loft in the other. If in fact the shapes are revolved, it's generally better to use a revolve.

  Hi S1mon, thanks for the post. I'm using Onshape for 3 month now, so this kind of comment are perfect. I will try to symplify everything.

  I can't do that, a weird red line appear and I cannot figure why Onshape is ponting only this one. I made the link public.

  I used the revolve and sweep tool. What do you mean?
