Ground To Parent

The Ground To Parent tool lets you define an inherent rigid relationship between a child component and its parent component so they move together in Fusion.

Use this tool when you want the child and parent components to move together in an assembly.

These component types are automatically grounded to their parent component when you create them:

• The first component you create in a design
• The first child component of any component
• A component that you Copy and Paste or Paste New

These component types can be ground to parent:

• Internal components
• External components

These component types cannot be ground to parent:

• Patterned components
• Mirrored components

Joints

If it is grounded to parent, the first component you select when you create a joint is automatically ungrounded from parent. The second component you select maintains its ground to parent status.

Existing assembly relationships

If a child component has an existing assembly relationship and you ground it to its parent component, the child component will move back to its initial position and any existing assembly features will need to be resolved. Ground To Parent will override the following assembly relationships:

• Rigid Groups
• Move
• Pin
• Capture Position

Ground To Parent and Pin

These two tools can seem similar but they have several key differences. Ground To Parent defines an inherent fixed relationship (similar to a rigid joint) between parent and child components while Pin fixes the component in place in the design itself.

When you pin a component:

• It is pinned in its current location to the top-level coordinate system of the design.
• A Pin feature is created in the timeline.

When you ground a child component to its parent:

• The child component moves back to its initial position when it was created or inserted into the design.
• The components move together.

Manufacturing Models

When you create a Manufacturing Model that contains components that have been ground to parent, any ground to parent relationships will be overridden. This lets you arrange the components for manufacturing. You can use Ground To Parent on any new components you create in the manufacturing model.
