In Catia and Nx cad, I have this problem. We create a helical spring using the separate helical commands and then add the spring wire diameter at teh end of helix, which is followed by the sweep command to generate the spring. When this spring is taken in to assembly i'm unable find specific surfaces for initiating the constraint.the most i can do is to constraint the central helical axis of the sprig to the axis of the component. then use the move command to move it up and don to the specific location. is there an easier ay to constraint the spring other than this?
1.create points on the diameter of the ends of the spring and mate them with the surface of support.
2.constraint the central helical axis of the sprig to the axis of the component.
