PRIME MOTIONThe timeline
Every sketch and feature you make is recorded, in order, on the timeline. The model you see is that list played from the start. Change an early step and everything after it is rebuilt on the change. Tap Time at the bottom of the view to show or hide the timeline strip, which runs across the top of the view.
With no features yet the strip says No features yet.
Moving the marker
The marker shows how far the list is played. Features past it are dimmed and not built, so you see the model as it was at that step.
- Tap a feature to move the marker to it, or use Roll to here in its menu.
- First, Back, Forward and Last step the marker; Play plays the build from the marker onward and Pause stops it.
New features are added at the marker. Move it back to Last before carrying on, unless you mean to insert a step.
Editing a feature
Double-tap a feature, or use Edit in its menu, to reopen its drawer with its values. Sketches, Extrude, Hole, Fillet, Chamfer and Machinable Joint can be edited this way; other features say ‹feature› has no parameter editor.
The feature menu
Long-press a feature for its menu, headed by its name:
| Item | What it does |
|---|---|
| Edit | Reopens the feature's drawer |
| Rename | Gives it a name of your own; clear the field to restore its natural name |
| Suppress / Unsuppress | Leaves it out of the build without deleting it. A suppressed feature is faded and struck through |
| Roll to here | Moves the marker to it |
| Group… | Gathers features into a named group |
| Ungroup (keep features) | For a feature in a group: breaks the group, keeping its features |
| Delete | Removes the feature and anything that depends on it |
| Delete all after here | Removes every feature past the marker, and anything depending on them |
A group's own menu has Rename group, Ungroup (keep features) and Delete group and features.
Every delete asks first and lists what goes, for example This removes 3 items — everything that depends on it: …. Each adds This cannot be undone by rolling back.; use Undo instead.
Reordering
Long-press a feature's handle and drag it along the strip. Only positions that keep every dependency intact are offered: a fillet cannot move before the extrude it rounds.
When a rebuild fails
After an edit, a feature that can no longer be built — a fillet whose edge has gone, for example — is tinted red with a dot. Its menu shows why, in red. A warning is shown in amber. Fix the feature, or the step before it, and the rest rebuild.
