SOLIDWORKS includes three integrated Motion solvers for creating videos and animations in assemblies. Animation and Basic Motion are included in every license of SOLIDWORKS, and Motion Analysis is available with SOLIDWORKS Premium or any SOLIDWORKS Simulation license. This tutorial series will help you understand the basic skills to get started even if you have never created animations before. Videos are broken down by topic for easy searching.

Motion Analyses use assembly mates to calculate motion and understand interactions and forces that result from the inputs. The SOLIDWORKS assembly environment is much more tolerant of excessive mates or mates that are marginally over-defined, but those same mates may cause the solver to create incorrect or inappropriate motion in some scenarios. Understanding degrees of freedom helps to understand what redundancies mean and how they can cause problems. Best practice for motion analysis involves simplifying rigid sub-assemblies and components to the bare minimum of components and mates to minimize redundancies and being skeptical of results until they can be verified as accurate.
