The timeline is the temporal interface for animation. The timeline is located to the right of the MotionManager design tree. The timeline displays the times and types of animation events in the motion study.
As you position the
, move components in the graphics area, add simulation elements, or change the
, the timeline displays changes using
The timeline is divided by vertical grid lines corresponding to numerical markers showing the time. The numerical markers start at 00:00:00. The time scale depends on the size of the window and on the zoom level.
To view the components at a particular time, click that time on the timeline. This sets the time bar to that time and displays a preview of the component positions.
When setting the time bar, do not click on a key point.
Shortcuts from the Timeline
After you position the time bar and make changes to a motion study, you can edit the animation by dragging the key points.
Right-click in the timeline area and select any of the following:
The new key properties match the current model state:
A red timeline indicates a motion solver failure. If the timeline is red, try one of the following:
Suppress or remove unnecessary mates.
Simplify the mates.
Specify the motion differently, for example, by using a motor instead of a component key.
Select and drag key points to move them along the timeline:
Ctrl + drag key points to copy them to a new time.
Drag the key (top row) to change the duration of the motion study without changing any of the other key point locations.
Alt + drag the key to scale the motion study, including any other key points.
Right-click any key point along the timeline to do the following:
Cut, Copy, Paste, or Delete. These functions are available with the following restrictions:
Select All. Available for any key points.
Multiple key points. Press and hold Ctrl to select more than one key point.
Select Reverse Path to reverse the animation of the entities that correspond to the selected key points:
Replace Key. Updates the model status for selected key points. For example, if you define an animation with a mate suppressed, and then unsuppress the mate, some key points may turn red because the mate, as it was defined earlier, prevents movement or visual changes.
To redefine the key:
Place time bar on the red key.
Right-click and select Replace Key.
Redefines the key to the position allowed by the mate.
Select an interpolation mode to control the acceleration or deceleration of a component or a visual property during the playback.
