What it does
- The Rollback bar (the blue line in Design Explorer) rolls the part back to any point in the feature history. Features below the bar are grey and are not calculated. Use it to insert a new feature before an existing one.
- Regen recalculates every feature (without the cache) and reports the time it took.
- Suppress turns a feature or sketch off temporarily.
Where to find it
- Model › Regenerate › Regen, Roll Back, Roll Fwd, Roll to End
- Drag the Rollback bar in Design Explorer (double-click the bar = Roll to End)
- Right-click a feature › Roll Back to Here / Roll Forward to Here
- Direct Edit › Edit › Suppress / Delete
