Structure tree


The Structure panel contains the Structure treeClosed, which shows you each of the objects in your design. Objects are displayed in the order in which they were created, or in the order in which they were imported. The figures below show all the object types that can be displayed in the Structure treeClosed.


The appearance of solid bodies in the Structure treeClosed will vary when they contain hidden faces or surface bodies.

Exploded Components

With the Default configuration active, there are no exploded components, so the AssemblyClosed name appears as shown below.


With a Non-Default configuration active, the assembly either has exploded components, or can be exploded, so “Exploded” is added to the assembly name.

You can use the Structure treeClosed to find objects, select objects, set object visibility, expand or collapse the nodes of the tree, rename objects, create, modify, move, replace, and delete objects, as well as work with components using the Structure treeClosed.

You can uncheck the box next to an object to hide it in the Design windowClosed.


Some objects, such as sketch curves and 3D curves, are automatically placed in Curves groups in the Structure treeClosed. You can rename a curve, but not the curve group. You can move the Curves group, but you cannot move a curve out of the group. Deleting the group deletes all the curves in the group.

You can set the visibility of a Curves group or an individual curve in the group, even if the CurveClosed group is within a dependent copy of a component.

To find objects

To find an object in the Design windowClosed, hover over an object in the Structure treeClosed to highlight it in the Design windowClosed. Hovering over a hidden object displays it temporarily in the Design windowClosed.

To find an object in the Structure treeClosed:

When Pattern is selected in the Structure treeClosed, the selection list updates to display the number of patterns included in the design.

To move objects

Drag an object or component to change its position in the Structure treeClosed.

Right-click an object and select MoveClosed to New ComponentClosed to create a component within the active component and move the object into it. If the object has a custom name, the new component will have the same name.

Ctrl+right-click multiple objects, then right-click and select MoveClosed Each to New Components to create a new component for each object within the active component and move the objects into the components. If the object has a custom name, the new component will have the same name.

You can move the view of a component from one drawing sheet to another by dragging the view in the Structure panel.


An annotation plane cannot be moved to a sub-component after you add dimensions because the references would be lost.

OffsetClosed , mirror, and shell relationships stay with a solid when it is moved to another component, unless the relationship would link two components when it is moved.

To set the visibility of objects using the Structure tree

To expand or collapse components

The top-level object displayed in the Structure treeClosed (called Design1 in the image above) is a component.

To expand components:

To collapse a component, click  or press ' - 'on the number pad.

To rename objects

Right-click an object in the Structure treeClosed and select Rename or press F2 to rename the selected object. You can also click the object, pause, then click again to rename it.

The top level component is automatically named when you first save your design, but you can rename it.

Multiple bodies selected in the Structure Tree can be renamed at once. The new name applies to the body for which it was entered. The remaining bodies are numerically incremented with a number appended to the name. This also applies to components.

To convert a solid to surfaces

  1. Right-click the solid in the Structure treeClosed.

  2. Select DetachClosed all.

    All faces on the solid will be detached from each other and will become surfaces.

To lock and unlock objects

Locking a solid or surface prevents any changes from being made to it.

  1. Right-click the object and select Lock from the context menu to lock the object.
  2. Select Lock again to unlock the object.
