I thought I'd check I'm not missing something before posting to the idea station.
Can I use the spring generator to design a spring for me? I know my spring rate, my loads and my dimensions. I don't care how many active coils the spring has as long as it perfroms to the specifications I've calculated. Can this approach be used, or am I misinterpreting this tool?
Perhaps you should try using the Compression Spring Component Generator (Assembly > Design tab > Spring panel > Compression?
It sounds like this tool does exactly what you are looking for.
This tool requires me to know the number of active coils and then attempts to extrapolate the information that I already know. I'd like to be able to input my physical envelope & behaviour (Max & min compressed lengths, max OD & min ID, max & min required forces) and have the generator return the required coils and whether there is a material suitable to provide the required behaviour. Is this currently possible?
I don't think what you want is possible with this Design Accelerator.
As I understand it there are two functions to the tool.
One is a modeler in which you enter physical specifications that you know
and the second function (entirely separate from the modeler) is a calculator that allows you to enter your specifications and lets you know the calculated parameters.
I think from there - you call a spring vendor and have them suggest an off-the-shelf spring or quote a custom spring.
