springs

Not sure when this happened but all the springs, made using a feature script, we named 'Spring Maker V2.1', are failing. If I go back to any earlier release or version the springs generate fine. The error I get is 'Spring Maker V2.1 did not generate properly; Could not create a valid swept body, check input.'

I'm not sure how to create this animation as I am quite new to CAD and I'd love some feedback.
