The step hierarchy is also known as the object list. It is a tree-like structure that helps the software decide how to link up objects and some of their parameters through a parent and child relationship.
Meaning of each icon type:
If the icon is white: you are in the Default State
If the icon is green: the object is linked to the Default State
If the icon is red: the object is not linked to the Default State
From the Step Hierarchy:
- You can see object relationships by clicking the arrow beside parent objects.
- You can show/hide the children by clicking on the arrow. Tip: Alt+Click the arrow to Expand/Collapse All Children.
- Child objects will be below and indented to the right of its parent. When a parent’s arrow points to the right the children are hidden.
- Right click the parent/child to use other available options e.g. copy, duplicate, cut, delete, isolate, hide and unhide.
Tip: you can also quickly duplicate an object by pressing shift + gizmo drag while moving an object in the Scene View.
- Select/Click on the parent or child to edit its properties in the Object Properties window.
- Finally, you can see triangles count/object count in the step hierarchy.
- ▲ - The total amount of triangles in this node and all of its descendants.
- ⌗ - The total number of descendants of this node.
Here is how to select parts of an object in the Step Hierarchy.
