which 3d modeler exports normal vector?

i use Anim8or to import 3DS files.
but after i save the model as AN8 file, there is no normal vector data in the file.
i need to make 3D models with thousands of polygons, without precalculated normal vector, the 3D model is useless.
which modeler should i use?

Anim8or doesn’t by default export normals,but allows it.
Go to the menu Options/Debug/Output Normals and select the option.

thanks a lot
