You can attach this component to a modeling component to show the projected path on which a component moves during an animation. For example, in the double pendulum image below, the traced paths indicate that the left rigid body moves in a circular path and the right rigid body moves along a curved path during an animation.
When the mode is set to Always visible (default), or Drawn over time, the fadeTime parameter does not appear in the Inspector panel.
To generate a trace connect the Path Trace component to the frame of one modeling component and run the simulation. The projected path of that connection point appears in the 3-D Workspace.
Note. To generate a new trace for another mode, the simulation must be re-run.
