Instances of `Box3` are axis-aligned so it’s normal that the bounding box varies in size when objects are rotated.

You could also try using Object Bounding Box [three.js/OBB.js at dev · mrdoob/three.js (github.com)](https://github.com/mrdoob/three.js/blob/f83bc569da527d2821a428ffaead8b29b5f847a5/examples/jsm/math/OBB.js)

If we import a mesh not axis aligned, when we correct her rotation and become axis aligned, bounding box wont update and still as initial before axis correction

Have you already tried `box.setFromObject( object, true )`?
