Components (Fusion 360)
Top-level containers in a Fusion 360 design that act like assemblies — components contain bodies and have their own origins, joints, and timelines.
Definition
A component is a self-contained design unit. Bodies inside a component move together when the component is joint-moved. Components can contain sub-components (recursive). Each component can be activated (in-context editing) so creation tools target it specifically.
Fusion 360 stores one component per saved 'Linked' file when you separate them; the parent design becomes a multi-file project. Linked components keep their own version history.
Why it matters
The decision 'is this geometry a component or a body?' shapes every downstream operation. Components are required for joints, motion, BOMs, multi-user collaboration; bodies are right for parts that don't need any of that.
Common pitfalls
- Modelling 20 parts as bodies in one component, then needing to add motion — refactoring is painful.
- Creating components for every small body — assembly tree becomes unmanageable.
- Not activating a component before adding features — features get added to the wrong component.
This concept is a core structural element of the Fusion 360 drafting and engineering environment developed by Autodesk. Autodesk's cloud-native unified design-and-make platform — parametric/direct hybrid modelling, CAM, sheet metal, simulation, electronics, and generative design in one subscription.
Relevant Fusion 360 FAQs
❓ Is Fusion 360 truly free for personal use?
Yes, but with restrictions. The personal-use tier is for hobbyists with under $1k/year in revenue from Fusion-created work. It limits active documents (10 editable at once), removes simulation/generative-design/electronics/extensions, simplifies CAM (no 5-axis, no multi-setup), and has restricted export options. Autodesk has progressively narrowed the free tier; verify current terms before relying on it commercially.
❓ What's the difference between Fusion 360 and Fusion Industry?
There is no separate 'Fusion Industry' product as of writing. 'Fusion 360' is the unified product. Extensions (Manufacturing, Simulation, Generative Design, etc.) add capability. Autodesk has also branded vertical packages (Fusion 360 with Inventor capability) at times; consult current Autodesk pricing pages.
❓ Can Fusion 360 work offline?
Yes — with caveats. Fusion caches files locally and supports a 'work offline' mode for up to 2 weeks. Cloud render, generative design, electronics simulation, and forced sync features require connectivity. For continuous offline work, Inventor is a better fit.
