 +This is the first tutorial in the Visual3D typical processing session, each of the tutorials will go over the sequence of steps involved in handling and analyzing data in the application. This specific tutorial will go over building a 6 DoF Model from a motion capture dataset.
  
-The techniques learned here will be consistent with all Visual3D models. However <b>the model described in this tutorial is only designed to illustrate the principles of model building and should not be considered the Default Visual3D lower-body model</b>. Once the User learns the basics of building models it is up to him or her to decide what model and marker set is most appropriate for their analyses. +</p><p>The techniques learned here will be consistent with all Visual3D models.
