Yes you have 2 methods for import OBj files

The Native one: Menu SUbD / Create /From a File but better to have only quads in the obj file!

Second is _Import OBJ by Max Smirnov : http://moi.maxsm.net/files/scripts/ImportObj.v.1.5.2015.09.10.zip

with this other one: only the wire by Michael Gibson: http://moi3d.com/download/Obj23dmWireframe.zip

150 000 Poly is a reasonable maximum
