Group objects
Organize objects under a parent while preserving separate meshes. Moving the group can move the assembly together.
Before you start
Select the objects that form an assembly in object mode. A group is a parent in the scene hierarchy; its children retain their own geometry and materials.
Use the operation
Keep related parts organized and transform them together.
- Select the parts and choose Group from the object context menu.
- Locate the new group in the scene tree and give it a useful assembly name.
- Select the group to move, rotate, or scale the assembly. Select a child when only one part should change.
- Use Ungroup when the hierarchy is no longer useful, then check that the parts retain their intended placement.
Controls and choices
| Controls | What changes |
|---|---|
| Parent selection | Transforms applied to the group affect its descendants. |
| Child selection | Edits a part independently within the parent's coordinate system. |
| Lock state | A locked object or ancestor can make an operation unavailable. Inspect the scene tree if a group cannot be edited. |
See what changes
Before
Two separate objects
After
One parent, two children
Check the result
Expand the group to confirm its members. Grouping should not change mesh topology or fuse touching parts. Avoid selecting both a parent and its descendant when preparing another grouping operation; select the intended hierarchy level.
