It does ? I haven't used it in ages, as it is useless for classic :p
For all intends and purpose I still recommend a proper 3D editor, as from what I can remember world studio is rather limited to primitives, thought you could import models to use with world studio, but that then rather defeats the purpose as meshes can be created in the 3d editor, also would have the benefit of creating far more complex shapes to use.
Nothing wrong with using world studio, it's true purpose wasn't to create models to export, but rather create complete maps to use with in a engine.
