Which tool would be best to use to create this tubular shape with different inner and outer section and then cut ellipsoid holes along its length?
As far as I understood, shell tool could easily cut holes in the tube, but morph tool couldn't.

Thank you!
wanted profile of the tube
wanted shape of holes in the tube
I agree with Haiku, probably the Morph Tool is the best option.
As I can see on the picture, the thickness of the Shell is not constant, it is thicker on the sides, thinner that the top and bottom. The Shell Tool can create only constant thickness structures. So probably the Morph Tool is the way to go.
in fact - it is a much more complex task to get such a form - because You would need an elliptical spiral to get the "cutout" in front.

There are some workarounds possible to do similar things with the railing-tool and its "inner tubes", but better would be to script a GDL-Tube for an elliptical spiral and make an SEO-cutout. Really not so easy..
You could make this with complex profile beams for the floor, complex profile walls for the walls, and another complex profile beam for the roof.
