Animation Dashboard - Overlay

Animation dashboard -> Overlay tab
Lets you play one animation on top of another animation. To help you see the two animations, you can change their color and offset one from the other. You'll find this helpful when you want to visually compare the results of two or more modeling changes.
 
Note:  
Each animation you overlay must have the same beginning, increment, and end times.
 
For the option:
Do the following:
Analysis
From the list, select the animations to be overlayed.
Offset
Enter the amount by which to offset the animations. Enter x, y, and z values. Adams PostProcessor applies the offset to each animation if you selected more than two animations to overlay.
Colors
Enter the colors in which to display the overlaid animation.
