Enter the diameter, x and y coordinates and a rotational direction of each pulley. After adding each pulley in your system, you can make corrections by clicking it in the list. You can delete or change the order by checking the box for the pulleys you wish to modify and using the menu to change he order or delete the selected pulleys. The checkbox at the top of the list allows you to mass check/uncheck if you have a long list of pulleys. You can also get a blueprint view of the pulley system to verify it appears correct.
