1) load the props into the scene. 2) open the hierarchy window. 3) drag and drop the props to form the required parent/child relationships. 4) click the "Create Figure" button 5) when prompted give the figure a name. It will be created for you and stored in your "New Figures" folder. You may need to search for that but it will be there. 6) load the new figure and test.

Hope that helps.
