Displaying deformable parts such as suspensions, bellows and springs in mechanisms like a clamp is a common requirement in assembly modeling. With other CAD systems, users are compelled to create multiple parts with the required lengths of the variations, store them separately, and use discrete parts as per the need of the target assembly. Solid Edge with synchronous technology allows you to design a part with a specified variable as driving, which makes the part adjustable. Check out this tutor
