Recalculating Normals did the trick. Thank you for the tip.

Hello I just started using the Cura slicing software and imported a .stl object. In the prepare window the object looks as intended (needs to be hollow on the inside, see picture one) However when I do a preview of the sliced object it is completely filled out. (see picture two) What do I have to change? Kind regards Olga
