Quickly generate high-performing design alternatives from a set of manufacturing and material constraints. The first constraint is related to global displacements, which are total motions of nodes in a model considered in a global coordinate system. Both design variants have remarkably similar parameters, like a minimum factor of safety or mass, but are completely different visually. If you are a new user of generative design and have no knowledge of how to create or run a generative design study, reference Fusion 360 Introduction to Generative Design.

If you add in more materials than are needed or more manufacturing variations, you increase the amount of computation required. Conversely, you’re paying for it, so if you have time, max out your options and see what comes back. The second is that loads and constraints can only be applied to the ‘preserved geometry’ that you have defined; this is absolutely key and might be the cause of some iteration during set-up. In other words, good planning is required upfront before a project begins. When you run the study with the Alternative Outcomes option selected, you will be able to use new features that are described in more detail later, and you may get some additional outcomes on top of the default ones.
Learner reviews
For those looking to explore new materials options, new manufacturing options or to open up their design engineering work to new ideas and experimentation, it’s a launchpad for new journeys. If there are things to look out for at this stage, the big one is the t-splines model, if you’re looking to use these parts directly. Typically, in an optimisation process, you have a mass reduction percentage, but with the Fusion 360 generative design approach, you don’t have a starting volume or mass, so you have a target mass that the system tries to achieve.
Benefits of generative design for manufacturing
Again, you have a set of common loads, including forces, pressures and bearing loads. This automatically restricts geometry to this shape – but it’s a shame to nail things down so firmly during early-stage experimentation. At the same time, it can be a challenge to consider your project in this new way and you may need to iterate your problem definition in order to fine-tune it. If you do have an explicit volume inside which you need to work, there is the option to give the system a starting volume. As always, if you have any questions about generative design in Fusion 360, please reach out to us at With your feedback and our continuous improvement efforts in mind, we’re announcing an updated generative design price structure that gives teams of all sizes and budgets a chance to experience its benefits.

The final number of outcomes may vary depending on the chosen study configuration; that is, manufacturing constraints, additional constraints like symmetry, etc. Thanks to the continuous work on design divergence, new Experimental Solvers offer up to four additional outcomes on top of the default ones for every study setup.

And then you would still have an enormous amount of processing to do in order to compute it and sift results. As we discussed at the outset, topology optimisation refines a singular form to an optimised state, typically using a singular material. Generative design in Fusion 360 is, by contrast, a platform for experimentation on a much grander scale. There is a natural instinct to compare this set of tools to the more common topology optimisation tools available in other systems (including Fusion 360) – and, at present, the results appear similar in nature. Compared to the ‘all-you-can-eat’ approach to engineering software, this is where things are heading. You might not like it (and I personally have a few issues with it), but it’s a good indication of the adjustments many users will need to make.
Once your load cases are in place, the next step is to start to define the material and manufacturing aspects of the project. One of the characteristics of the new Experimental Solvers is increased variety of shapes. Thanks to new ways of optimization, the results you get for the same study setup can differ significantly in terms of the form while continuing to meet the optimization objectives. This gives you the freedom to choose the design based on its aesthetic values and not only mechanical properties.
It’s also worth noting that the Generative Design Workspace contains a sub-set of tools to help you abstract a model from an existing set of parts. This is useful for making smaller edits as you go through this period of iteration. Autodesk has been talking about generative design for quite a while now, stretching back to 2014, when executives began hinting at a future technology research project called ‘Dreamcatcher’.
Reimagine product quality in manufacturing
Experimental Generative Solvers and Features is a preview feature available in Fusion 360. Additionally, Experimental Solvers and Features improves the robustness and performance of generative design solutions. At this point, it’s worth considering what the generative design technology in Fusion 360 is actually doing. It is taking your load case and geometry and creating a matrix of studies that sees every material option run through with every manufacturing option you’ve selected. If you max the system out by selecting the maximum allowable materials and clicking on every production option, you’re likely looking at a 10×10 matrix; in other words, 100 optimisation runs at $0.25 each. Over these past few years, you’ve watched us expand our functionality to include additional manufacturing methods, load and constraint types, and performance objectives.
The Experimental Solvers feature is a part of generative design which is available to every Fusion 360 user. To open the Generative Design Workspace inside Fusion 360, you need to navigate to the Generative Design option (2) inside the workspace selector (1) in the upper left corner of the Fusion 360 window. With Experimental Solvers and Features, we can get more control over it by constraining allowable displacements. The improved algorithms of Experimental Solvers provide the possibility to remove the material also from the inside if it makes sense for a given model. This allows for faster optimization in some of the cases and produces the shapes that are more optimal from an engineering point of view.

In the traditional generative design approach, we can see the maximum displacement of the generated outcome, but we are unable to directly impact it before the post-processing stage. This means every user of the generative design feature will also see new outcomes with new sophisticated shapes, in addition to the existing traditional solutions. This technology brings new functionalities and delivers forms optimized in a new way, opening doors that have been closed previously. In addition to showing how to use the new technology of generative design in Fusion 360, above all, we will present how the new functionalities empower the new applications using real-world examples. Generative design in Fusion 360 gives you the ability to select multiple manufacturing methods to quickly explore numerous solutions for your design and engineering challenges. All in all, what Autodesk has delivered on here, in its first pass, is pretty damned impressive.

The generative design process explores manufacturing-ready outcomes earlier in your production process, optimized for cost, material, and different manufacturing techniques, so you can get to market faster. The mesh is just as you would expect – a high-resolution triangulated mesh of the result set. These are the constraints that control how the system should approach building geometry to solve your loading conditions.
Thankfully, the hype train came to the end of the line towards the end of last year, when the Fusion 360 team finally updated the system to include the first variant of this technology as a real-world, commercially available product. After opening the results in the Explore tab, you can identify the outcomes that were generated by Experimental Solvers by the flask icon in the upper right corner of the outcome thumbnail. Inside the Preferences window, find the Preview Features option (5) and then make sure that under the Generative Design tab you have selected Experimental Generative Solvers and Features (6). The green parts are preserve geometries while the yellow part is a starting shape.
