You can create motion studies from a Motion Study tab for a SOLIDWORKS model. When you open the motion study, you can use the MotionManager tools to define the motion of the mechanism. The MotionManager tree lists the model features. The most basic method of defining motion is to modify the feature position, appearance, or other properties in time. You can define an animation by adding keypoints along the MotionManager timeline for selected features, and modifying the properties of those features at the keypoints.
