I want to create a spring with both closed and ground ends using a family table. Most of our company's springs are purchased from Lee Spring Co. andthey only supply OD, Wire Dia, Free Length, Spring Rate, and Solid Height. I need to be able to figure out the total number of coils based on this info to include in the part relations. Is there a formula? Does anyone have a similar Pro/E model or know where I can download one?
