The Feature Tree and History
Editing features
- Double-click a feature, or right-click ▸ Edit Feature, to open its Property panel.
- Select a feature and press Del (or Edit ▸ Delete) to delete it.
- Edit ▸ Undo / Redo (Ctrl+Z / Ctrl+Y) works on the whole part history.
- Rebuild (Ctrl+B, or the quick button) rebuilds the part.
- A feature that fails shows an error in the tree so you can fix or re-pick its references (see Fix References).
References that follow edits
Features that use picked edges and faces (fillets, chamfers, shells, drafts, axes…) find them again after the model changes. An edge remembers the faces on its two sides and whether it is an outside or inside corner. When a dimension moves it so far that other edges now lie nearer its old place, the right edge is still found, and an edge of another kind is not taken for it. A face that moved is found as the face facing the same way that is clearly nearest. A reference found again this way is updated, so it keeps following the model.
Fix References
Tools ▸ Fix References… lists every feature that failed to rebuild, what went wrong and which of its edges or faces are no longer in the model. Open it also by clicking the red error count in the status bar, or by right-clicking a failed feature. For each feature:
| Button | What it does |
|---|---|
| Edit | Opens the feature (or sketch) to pick its references again |
| Remove missing | Keeps the references that are still found and drops the others |
| Suppress | Leaves the feature out for now |
Fix them from the top: a feature can fail only because one above it did. The list follows every rebuild while it is open.
Rollback bar
The blue line at the bottom of the tree. Drag it up, or right-click a feature ▸ Roll Back / Roll to End. Features below the bar are suppressed, and new features are inserted above it.
Reordering features
Drag a feature up or down the tree. Its absorbed sketch moves with it. A move that would break a reference is refused with the reason.
Reference arrows
Select a feature in the tree. Blue arrows come from what it uses; purple arrows go to what uses it.
Tree symbols
Sheet metal features and bodies have their own icons. Under-defined sketches show (-). Sketches absorbed by features are hidden by default.
