Bom Fusion 360

2/14/2022by admin

A lot of users new to CAD or new to a 3D CAD modeller may be confused by the concept of Fusion 360 Bodies and Components. You don’t know, what you don’t know right? For those users, bodies and components can appear to be too similar to one another, and keeping things organised can be a challenge. So what’s the story? What are the differences between Fusion 360’s Bodies and Components, and when should Components be used?

Fusion 360 Bodies vs Components


Use third-party BOM Application Download and install a third-party application for Fusion 360 that allows to create a multi-level parts list, for example: OpenBOM for Autodesk Fusion 360.

Bodies are essentially collections of 3 dimensional features connected to one another, until they form a static representation of a part. People can create multiple bodies within a Component. Modern Top down design methodologies use the concept of bodies as the bed rock of its power. Essentially you are modelling one body relative to the next, as they will be built in the real world, allowing users to ‘borrow’ geometry from one body to drive features on the next. It’s a very powerful and convenient way to model.

  • Collections of features
  • Predominantly used with Top-Down modelling techniques
  • Geometry from one body can be used to drive geometry on another
  • Perfect for ‘fleshing out’ your design in the conceptual stages of the process
  • You can have more than one body per component
  • Bodies can be promoted to Components
  • Typically you would only have one body per component during the final stages of design
  • You CAN’T create Joints between Bodies


First of all, you need to understand that as soon as you create a new Fusion design, it is already a Component, additionally it will always be the top level Component for the design. Then by default the first 3D features you create will start to form the first Body for the design and therefore the Component. Components can contain one or multiple bodies. Typically though, as your design takes shape and you move into creating movement within your model, you would only expect to see a single body in each component.

Components can represent either parts or sub-assemblies, so naturally sub-assembly components will be made up of other components. Building the component structure is how you communicate to the tradesman reading your drawings, or viewing your model, how you want them to assemble your design. Any downstream user of your designs will benefit from what is in fact, the Bill of Materials for your product. This structure cannot be achieved with bodies alone. Properties are a huge part of BOM’s as well, so components allow users to enter custom property values for Part Number, Part Name and Description. More properties and the ability to create custom properties will no doubt be added to Fusion 360 Components in the future.

  • OpenBOM is a natively integrated with Autodesk Fusion 360 provides an easy way to capture information from Fusion 360, seamless Google-like editing, and collaboration as well as powerful calculations and planning capabilities.
  • Export BOM/Parts List to excel or other format In order to get BOM and Parts Lists into ERP and other systems, it would be helpful to be able to export those directly from a Fusion drawing. Currently, you can do this by exporting the entire drawing to DWG, then using 'TABLEEXPORT' in AutoCAD to get it to a CSV file, but its a bit of extra work.
  • Any new Fusion design is always a Component in it’s own right.
  • You can only create Joints between Components
  • Components can contain other components to form sub-assemblies
  • Defining components allows you to create a Bill of Materials (BOM)
  • Custom values for properties can be assigned to individual Components
  • Drawings are associated with components
  • Components can’t be demoted to bodies
  • Positional representations can be created, allowing a single component in multiple positions to determine the geometry of a neighboring component
  • Components are used in the animation and simulation environments

Fusion 360 Bodies and Components in Summary

So, essentially Bodies form the geometric representation of your designs, either independently or as a result of relationships with other Bodies.Then Components allow you to define an assembly structure, and via the use of Joints, you can determine how parts and sub-assemblies function with respect to one another. When working with Components, you need to make sure you have the Component you are working with activated, otherwise you may get unexpected results. Just remember that the Fusion Design file is a Component of its own, so any additional features you add may end up as part of the top level Component, instead of the Component you thought you were adding it to. If you would like any further clarification, have any questions or tips about using Fusion 360 Bodies and Components, then please don’t hesitate to fire away in the comments below.


Oh, AND!!

If you are wondering what Top Down design is, Paul Munford wrote a great piece explaining the various assembly modelling techniques within the context of Autodesk Inventor. The concepts discussed also apply for SolidWorks, and of course Fusion 360. The only difference is Fusion 360 doesn’t explicitly label components as parts and assemblies.

LAS VEGAS, NV, Nov 20, 2019 – OpenBOM, a modern SaaS multi-tenant data management, and real-time collaboration service, announced the enhancement of OpenBOM integrations with Autodesk line of products including Autodesk Fusion360, Autodesk Eagle and Autodesk Inventor. By doing so, OpenBOM offers unmatched capabilities to manage Parts, Bill of Materials, Vendors, and Purchase Orders and streamlining design to purchase process for engineering prototyping teams and small-to-medium sized manufacturing companies. Unmatched real-time collaboration capabilities of OpenBOM combined with unique data management and availability of OpenBOM from Amazon Web Service infrastructure makes OpenBOM available for teams and manufacturing companies across the globe.

Autodesk strategy of cloud platform development is well aligned with OpenBOM multi-tenant SaaS data management and Bill of Materials management capabilities helping manufacturing companies to organize product data, collaborate in real-time and plan purchase orders. “Expanding Autodesk Fusion360 integrations and offering an improved user experience and support Fusion360 drawings dramatically expanding customer workflows. Combined with Autodesk Eagle and Autodesk Inventor integrations, OpenBOM is providing a unique way to manage purchases and collaborate using a multi-disciplinary BOMs,” said Oleg Shilovitsky, CEO and co-founder of OpenBOM.

“With this announcement, OpenBOM provides the Autodesk customers an easy and powerful way to manage downstream BOM management and purchasing process,” says Jim Quanci, senior director of Autodesk Development Network.

Marc Schomann a developer of Blackbox Open Source Tool Changing 3D Printer is using Autodesk Fusion 360 and OpenBOM. The team designs entirely with Autodesk Fusion 360 then captures product structure, item, and vendor information using OpenBOM’s purpose-built Fusion 360 Addin where they create and maintain all the related Catalogs and Bills of Material for the project. Later, the team shares it all to the open-source community using OpenBOM’s powerful Share function – there are no Excel files or emailing of designs here – it’s all in the Cloud with Fusion 360 and OpenBOM!

“Our distributed team used OpenBOM to capture product structure and assembly and part data from Autodesk Fusion 360 then create bills of material for purchasing the components we needed to build the printer,” Marc said. “The OpenBOM Fusion 360 integration made it easy to create and update BOMs and Part Catalogs and to identify and specify vendors as the design moved forward.”
