About Animation
Use the Application > Animation command to invoke the Design Animation option. With Design Animation, you can coordinate the components of an animation sequence and play back an animation.  
  
When you select this command, a timeline window appears below the graphics window, and a toolbar appears below the Pro/ENGINEER toolbar. You can run, create, and manage your animation using the menu commands, the toolbar buttons, or the timeline window.  
  
You can use Design Animation to do the following:
  
·  Visualize your assembly's operation. If you have the concept, but have not defined the mechanics, you can drag bodies to different positions and take snapshots to create an animation.  
  
·  Create an assembly or disassembly sequence animation of your model.
  
·  Create a maintenance sequence, a short animation of steps to take to instruct a user in how to repair or build a product.
  
For an introduction and overview of the Design Animation module, and for typical steps to take to create an animation, see the Design Animation Concepts Guide online document.
