PRIME MOTIONThe timeline
The Time chip opens the record of how the part was built: every sketch and every feature, in the order they happened.
It is a working tool, not a log.
Rolling back
Tap a step to move the model back to how it looked at that moment. Everything after it is temporarily set aside.
This is how you insert a feature earlier in the sequence than the end — roll back, add it, roll forward again.
Tapping a step also selects what it produced, so you can see which body came from where.
Reordering
Drag a step to move it. The design rebuilds in the new order.
Suppressing
Suppress a step and the model rebuilds without it. Useful for seeing the part without a fillet, or temporarily setting aside a feature you are unsure about.
Suppression sticks — it is a property of the feature, not a view setting, so it survives closing the design.
Grouping
Related features can be grouped and collapsed to a single chip, which makes a long timeline readable. Dissolving a group can either keep the features or delete them, and the app asks which.
When something breaks
A feature that fails to rebuild is marked in the timeline.
Playing through
The play control steps the marker along the timeline, rebuilding as it goes — a quick way to see how a part was constructed, or to hand someone else the reasoning behind it.
