How do I import 3D models into Alice 3.2?

[Alexis0602]

I have been working on an Alice program (in Alice 3.2) for my computer project and I have been trying to find how to import my own 3D models that I have downloaded or created and then use them as an object in alice 3. I cannot find a way to import besides the resource manager which won't let me insert my 3D models into the world I am creating. Thank you to all who reply.
