The Timeline records each Feature you use to create your design and captures its parametric history in Fusion.
Since it captures parametric history, the Timeline is only available in Parametric Modeling Mode.
Features are the foundation of your design. They capture the creation of every object and modifications to the design. Examples of when a feature is created:
To organize features, you can:
When you create a Feature, you specify Parameters to define the feature.
There are a few ways to edit feature parameters:
You can Suppress Features in the timeline to turn off the edit without deleting it. If the feature has any downstream dependent features, those are also suppressed.
To turn the feature back on, right-click and select Unsuppress Features to reenable the feature and any downstream dependent features that were also suppressed.
You can drag features forward or backward in time. If a feature is depending on another feature earlier in the timeline, you can't move it before the upstream feature.
For example, if you create a box and then add a fillet to it, you can't move the fillet feature before the box creation feature in the timeline.
Use Timeline Settings > Component Color Swatch to color code components in the Browser and their corresponding Features in the Timeline.
When you activate a Component in the Browser, the Timeline filters to show Features that are created and modify geometry in that Component.
You can drag the timeline Marker around in the the timeline to view the design at that point.
Use the buttons to the left to move the Timeline Marker to the beginning or the end, play through all features in the Timeline, or step through the individual features.
