Dave,
As you are still having trouble with the spring design tool, can I suggest that you go to the Traceparts.com web site and search for “tension springs” which will give you the choice of CAD models from which to choose. Almost any format is catered for, including Solid Edge. You may have to register in order to download, I can’t remember. If that is the case and you don’t want to, pick which one you want and PM me your email and I’ll download it for you and forward the file to you.
I use the Traceparts site quite a bit and, to save searching through pages and pages of parts, I often find something generically similar and then stretch or squash with the scale facility to obtain the size that I require. Probably not the preferred way to do things, but it works for me.
