creating a batch file for 3dsspp does not require the user to build a visual3d model because 3dsspp is not looking for a model, but for a set of projected angles between sets of 3 markers. because no model is used, visual3d is unable to render a body in the 3d animation window.
in order to visualize a simple skeleton in visual3d, you might consider recording a standing trial. to create the visual3d model see:
