Watched an nice instruction on creating a Spring, this example is one method, however I want to have 1 1/2 - 2 turns at the TOP & BOTTOM, know that I need to edit the design to add those feature with the 'VARIABLE' comand, however I cannot find it within the 'SWEEP' command as the Utube instructions explain, therefore I'm asking for some assistance to find out how to get to the 'VARIABLE' comand.
