Is it a static (non-animated) mesh? If so the standard command LoadMesh works. You may need to scale the mesh/entity to bring it into camera view if it's massive.
Or scale it down in 3ds (probably better).
obj=LoadMesh("filename.3ds")
PositionEntity obj,0,0,5 ; move away from camera
... or whatever
