# Product Structure Right-click Menus > Contextual menu actions available in the Product Structure panel The Product Structure offers actions accessible from contextual menus (right-click). Depending on whether one occurrence, multiple occurrences, or no occurrence are selected, the contextual menu is different. ## With nothing Selected ![No selection context menu](/api/media?file=/asset-transformer-studio/2026.5.0/media/STUDIO_ContextualMenu_PS-Selection-No.jpg) | Menu option | Description | | -------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | **Expand All** | Expands all the occurrences of the tree recursively, all at once.**Warning**: When the scene contains very large and complex models (thousands of occurrences and millions of triangles), expanding the whole tree might take a long time. | | **Collapse All** | Folds all the occurrences of the tree, all at once. | | **Show All** | Shows all the occurrences of the tree, by setting each occurrence's visibility (or `Visible` property) to `Inherited` value. | | [**Create Occurrence(s)**](/asset-transformer-studio/2026.5.0/api/python/scene_functions.md#createoccurrences) | Creates one empty occurrence, child to the `Root` node and with the name defined in the dialog box parameter. | ## With one Occurrence Selected ![One selection context menu](/api/media?file=/asset-transformer-studio/2026.5.0/media/STUDIO_ContextualMenu_PS-Selection-Yes.jpg) | Menu option | Description | Keyboard Shortcut | | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------- | | **Rename** | Renames a selection of occurrences (all selected occurrences will be renamed with the same name at once). | F2 | | **Expand All** | Expands all the occurrences of the tree recursively.**Warning**: When the scene contains very large and complex models, expanding the whole tree might take a long time. | | | **Expand Children** | Expands all the child occurrences of the selected occurrences, recursively.**Warning**: Expanding a subassembly with a lot of occurrences might take a long time. | | | **Collapse All** | Folds all the occurrences of the tree, all at once. | | | **Collapse Children** | Folds all the child occurrences of the selected occurrences. | | | **Show in Product Structure** | Used to define which occurrence properties can be defined as a [Fast Property](/asset-transformer-studio/2026.5.0/manual/user-interface/window/product-structure-tree/customizing-the-product-structure.md). | | | [**Show**](/asset-transformer-studio/2026.5.0/api/python/scene_functions.md#show) | Shows the selected occurrences, by setting each selected occurrence's visibility to `True`. | S | | **Show All** | Shows all the occurrences of the tree, by setting each occurrence's visibility to `Inherited`. | | | [**Hide**](/asset-transformer-studio/2026.5.0/api/python/scene_functions.md#hide) | Hides the selected occurrences, by setting each selected occurrence's visibility to `False`. | H | | **Invert Visibility** | Inverts the selected occurrences' visibility. | I | | [**Flip Up-axis from Z-up to Y-up**](/asset-transformer-studio/2026.5.0/api/python/scene_functions.md#applytransformation) | Rotates the selected occurrence -90° on the X axis, to flip a model originally imported with a Z-up orientation (Asset Transformer Studio is Y-up oriented).**Tip**: This is a shortcut to the **Apply Transform** function, accessible from the [Scene](/asset-transformer-studio/2026.5.0/manual/user-interface/menu-bar/scene-menu.md) menu or the [Function List](/asset-transformer-studio/2026.5.0/manual/user-interface/menu-bar/edit-menu/function-list.md) (F12). | | | [**Revert Up-axis from Y-up to Z-up**](/asset-transformer-studio/2026.5.0/api/python/scene_functions.md#applytransformation) | Rotates the selected occurrence +90° on the X axis, reverting a **Flip Up-axis** action.**Tip**: This is a shortcut to the **Apply Transform** function, accessible from the [Scene](/asset-transformer-studio/2026.5.0/manual/user-interface/menu-bar/scene-menu.md) menu or the [Function List](/asset-transformer-studio/2026.5.0/manual/user-interface/menu-bar/edit-menu/function-list.md) (F12). | | | [**Create Occurrence(s)**](/asset-transformer-studio/2026.5.0/api/python/scene_functions.md#createoccurrences) | Creates one empty child occurrence for each occurrence of the selection.**Note**: This is different from **Create Empty Occurrence** in the [Create](/asset-transformer-studio/2026.5.0/manual/user-interface/menu-bar/create-menu.md) menu, which works for one selected occurrence only. | | | [**Create Occurrence From Selection**](/asset-transformer-studio/2026.5.0/api/python/scene_functions.md#createoccurrencefromselection) | Creates a new occurrence parenting the selected occurrences, grouping them. | | | [**Move Occurrences In Tree**](/asset-transformer-studio/2026.5.0/api/python/scene_functions.md#moveoccurrences) | Moves the selected occurrences in the tree by parenting them to the `Destination` occurrence.**Tip**: This can also be done by drag-and-dropping occurrences in the Product Structure. | | | **Snap to Ground** | Positions the selected [part](/asset-transformer-studio/2026.5.0/manual/data-preparation-fundamentals/about-occurrences/occurrence-types.md) on the ground (the whole selection, not each part individually).![Snap to ground](/api/media?file=/asset-transformer-studio/2026.5.0/media/STUDIO_SnapToGround.gif) | | | **Center to Origin** | Positions the selected [part](/asset-transformer-studio/2026.5.0/manual/data-preparation-fundamentals/about-occurrences/occurrence-types.md) at the origin of the scene (the whole selection, not each part individually).![Center to origin](/api/media?file=/asset-transformer-studio/2026.5.0/media/STUDIO_CenterToOrigin.gif) | | | [**Transform Pivot Points**](/asset-transformer-studio/2026.5.0/manual/user-interface/window/product-structure-tree/product-structure-right-click-menus/transform-pivot-point-menu.md) | Used to manage the pivot point of the selected occurrences. | | | [**Re-Tessellate**](/asset-transformer-studio/2026.5.0/manual/user-interface/window/product-structure-tree/product-structure-right-click-menus/re-tessellate-menu.md) | Lists functions used to manage retessellation capabilities. | | | **Export Selection** | Exports the selected occurrences to a supported file format. | | | [**Delete Selection**](/asset-transformer-studio/2026.5.0/api/python/scene_functions.md#deleteselection) | Deletes the selected occurrences. | DEL | | **Select Ancestor** | Selects the first common ancestor of the current selection. | \< | | **Select Children** | Selects the children for each occurrence of the current selection. | > | | [**Select Instances**](/asset-transformer-studio/2026.5.0/api/python/scene_functions.md#getinstances) | Selects all the instances of the currently selected occurrence. | | ## With Multiple Occurrences Selected
