Set the origin
Move the object’s origin to its geometry center while preserving the world-space position of every vertex.
Before you start
Select a mesh in object mode. Use Reset Origin when its pivot should be at the center of its geometry bounds. The current command recenters the origin; it does not provide an arbitrary pivot-placement dialog.
Use the operation
Recenter the pivot before rotating or scaling a part.
- Select the mesh and inspect the position of its transform gizmo relative to the visible geometry.
- Choose Reset Origin from the object context menu.
- Confirm that the origin moves to the center of the mesh's local geometry bounds while the visible geometry stays in place.
- Try a small rotation to check the new pivot, then undo that rotation if it was only a positioning check.
Controls and choices
| Controls | What changes |
|---|---|
| Geometry bounds | The command uses the local bounding-box center, which can differ from the center of mass or a visually preferred hinge point. |
| Object position | The position compensates for the geometry offset so the visible mesh retains its world placement. |
| Apply transforms | Baking transforms is a different operation. Choose it only when you also need to normalize transform values. |

Check the result
Check that the mesh did not visibly shift and that the new pivot is useful for the next transform. A long protrusion can pull the bounding-box center away from the main body. For a hinge or a shared assembly center, a parent group can provide a more suitable transform context.
