Rotate object in volume CUBE

Hello!

I’m not sure if the title says what I want to resolve but i’m looking to find a way to make sure that the objects imported can be rotated and maybe reset the axes or do something so that my object does not stays at an angle in the “virtual space”

As you can see in this picture, the objects is slightly rotated where the object itself is straight.

Either you align the axes to the object, or you rotate the object and align it to the bounding box.
