As Robert says there are no stored coordinates You could write a node visitor to traverse the tree of node of your 3ds model once it has loaded and walk thru all the bounding boxes to calculate a center for the 3d model. But his would be the center of the geometry, and not necessarily what he modeler considered the origin center of the model
