I have had no luck but been trying to set a limit mate to make this spring funcational in a model. i have 2 planes at each end and was thinking about using a distance limit mate and that should allow me to have the spring fully funcational. it currently springs back and forth but with no limit ideals?
Create one dummy part with no geometry. Insert that into assembly and set one of plane at required distance limit mate.
Now set/mate the spring parts accordingly.
