For complex designs/assemblies, I rely on Solidworks. It’s the gold standard, really precise and reliable for detailed projects. Been using it for many years, and it’s solid for heavy tasks with many components. One feature I find very useful is the “Advanced Mate”—this allows for creating more complex and controlled assembly relationships, very specific to SolidWorks. The depth of tools, such as simulating real-world physics within an assembly, is something I appreciate.

Fusion is good, but when it comes to the engineering depth and precision need, SolidWorks, with its unique capabilities, remains my choice. Maybe it’s a matter of taste, but still!

Hi, I would mention the following. SolidWorks: More mature, robust for complex assemblies, better suited for large-scale projects, higher learning curve, requires powerful hardware. Fusion: Cloud-based collaboration, easier learning curve, integrated CAM and simulation tools, suitable for startups and smaller teams.
Additionally, when we look at the cost, SolidWorks generally costs more because it’s made for experts and big companies that need its detailed tools for complicated work. On the other side, Fusion 360 has pricing that’s easier to get into. It even has a free option for people doing it as a hobby, new companies, schools.. Plus, its pay-as-you-go plan is liked by smaller companies and individual workers

btw this is a good article comparing both  https://all3dp.com/2/fusion-360-vs-solidworks-cad-software-compared-side-by-side/

I agree with the comments already made about when/how Solidworks is used vs. Fusion on assemblies. Solidworks definitely has more mature tools available and is typically more responsive when you’re spinning the integrated assembly. It also has great tools specific to using profiled structures and weldments.

Fusion’s advantage is in accessibility and price. It is still a robust CAD platform that is often an order of magnitude cheaper to access. I can’t use it for our work because it’s cloud-based, and we work on export-restricted projects with strict IT limitations (I’m in the US, so ITAR, for example). I have worked with collaborative projects with Autodesk and like their sharing options for viewing, commenting, and editing. Being invited to a project is great and allows you to dive in with others quickly. I don’t feel those collaboration tools are as convenient with Solidworks.

I lean more towards Fusion 360 for designing complex assemblies. Its integrated workflow and innovative features like generative design make it ideal for handling intricate projects. Plus, Fusion 360’s cloud-based collaboration ensures smooth teamwork. And yes, the more accessible pricing is definitely a bonus for me.
