SWIFT 3D and .EPS

When you export images from flash in eps format and then import into swift 3d you end up with this flat object. What I want to know is how do people then manage to make whole scenes 3d (with swift 3d only), all that matrix stuff , camera pan, etc with images that they made in flash (e.g. a rotating stick figure that was obviously drawn in flash). As far as I’ve tried I can’t figure out how your supposed to do this. Thanks in advance :).
