As a follow-up to this topic
I played around with the compressed spring from Curves WB. Great thing and easy to handle!
Nevertheless I have some questions/comments:
It took a while until I realized that I had to reduce the angular deflection to get reasonable results, so this may be pointed out in the documentation.
I can see what increasing flatness does, but I would like to know a bit more. How many turns are affected, is it only the last one? Does it take more computing power if the value is raised (it feels so)?
Is it possible to have decimals for the number of turns?
