Roll back, edit and suppress steps on the timeline
The timeline under the view lists every step that built your model, in order. Click a step to see the model as it was then, change a step's numbers and everything after it rebuilds, or suppress a step to try the model without it.
-
Each button on the timeline is one step, oldest on the left. Click a step — here 1. Plate — to roll the model back to it. Later steps fade, and anything you make now goes in at that point.

-
Click Show every step, at the end of the arrows beside the timeline, to bring the whole model back.

-
To edit a step, select its body — here the rib — and change a value in the inspector. Type 450 for the Height and press Enter: the step is rebuilt, and so is everything after it.

-
To try the model without a step, right-click it on the timeline (or focus it and press Shift+F10) and choose Suppress. The step stays in the timeline, struck through, and its body disappears until you Unsuppress it.

Good to know
- Drag a step along the timeline to build it at another point; the timeline refuses a move that would put a step before what it is built from.
- The step's menu also groups steps, and moves a step earlier, later or to the start.
- Turn on Roll back for me only to roll back without changing what other people working on the model see.
