The rollback feature allows you to return to a specific point in the timeline and make edits, facilitating design iteration and exploration. 
  1. Edit in Place: Fusion 360 enables you to edit components in the context of an assembly or a higher-level design. By selecting a component and choosing the edit in place option, you can change the selected component while considering its interaction with other parts in the assembly. This tool allows for downstream design changes without breaking the overall design intent. 
  1. Direct Editing: Fusion 360 offers direct editing capabilities, allowing you to modify the geometry directly without relying solely on parametric features. Easily push, pull, move, or resize faces, edges, or vertices, making quick changes to your model when needed. 
  1. Design Changes and Updating: Fusion 360 provides robust tools for managing design changes and updating associated components or assemblies. When modifications are made to a part or feature, Fusion 360 automatically updates dependent components, maintaining design intent. The ability to track and propagate changes across an entire design ensures consistency and efficiency when making modifications. 

These tools empower you to create parametric models that are flexible, efficient, and adaptable to design iterations and downstream changes. 

Considerations When Using Parametric Modeling

These techniques help ensure that your assemblies are properly constrained, components interact as intended, and your models are easily modifiable, allowing for efficient design revisions and updates.
