Bulletsharp Output?

I am using Bulletsharp with a Sharpdx rendering engine. I am trying to get the output from the world after I step the simulation

    public bool Frame(float timeStep, List<DModel> Models)
    {
        world.StepSimulation(1 / 60);
        foreach (DModel model in Models)
        {
            Matrix transform;

            Objs[model].GetWorldTransform(out transform);
        }

        return true;
    }

most people do transform.Origin but that just returns 0, 0, 0

I'm trying to find the different positions that come out of the world
