Expected behavior

What should have happened?

I had a lathe operation, plus 2 extra extrusions (one with 3x time rotating symmetry) acting as a difference.

At the end I wanted to see a crossection, so I did another sketch, extruded it, and used as a difference.

I expected to have a solid model, not hollow one, with some red marks on the edges. There are some other red marks, that I don't know what they are, and some edges (45 deg ones) do not have the red edges.

No idea what is going on.
