Fusion combines the steps of making a physical product in one application. You model parts and assemblies in 3D, run simulations to test stress and heat, and generate toolpaths for CNC machines and 3D printers. It also includes electronics design and drawing tools. Because it runs with cloud-connected data, teams can share designs and collaborate, and it works on both Windows and macOS. Product designers, engineers, machinists, and hobbyists all use it.
Generative design is the main AI feature. You set the loads, materials, and manufacturing constraints, and the software explores many shapes that meet them, often producing organic forms that use less material than a conventional design. Other automation helps with drawings, sketching, and manufacturing setup. Engineers then evaluate the options and choose one for production.
Fusion is sold by subscription for commercial users, with a limited free option for personal, non-commercial use and for qualifying startups and students. Some advanced capabilities, such as extended simulation and generative design, cost extra. It is easier to learn than heavyweight packages like SolidWorks, CATIA, or Siemens NX, but less capable for very large assemblies. Onshape is a browser-based rival, and FreeCAD is open source. For small shops and makers, it is the most popular all-in-one tool.
