This tutorial will show you how to create a dynamic spring that can compress and expand in context of an assembly. This type of model is suitable to be used in animations or in a flexible assembly.

Note: This type of dynamic spring cannot be used for simulation or motion and will not act upon the assembly. This method of modelling is purely cosmetic.

The spring is controlled by the length of the first sketch line which is driven by a coincident relation to another part in the assembly. When the assembly is rebuild SOLIDWORKS will recalculate the length of this line and adjust the sweep accordingly.
