One of the first things I did when starting to use the AnyBody Modeling System, was to understand how to configure the human model. This means enabling and disabling different body parts and setting up the available options for muscles, ligaments etc. The model is configured in AnyScript by defining switches which we call Body Model (BM) statements.
