Autodesk Fusion (formerly Fusion 360)
Fusion 360 is the Autodesk integrated CAD/CAM/CAE platform — battery teams use it for pack-enclosure design, fixture design for cell-tab welding, and the small-volume mechanical work where SolidWorks would be overkill. As a hard skill it requires parametric modeling fluency, assembly constraints, drawing generation to ASME Y14.5, and the integrated CAM capability for prototype fixtures that need machining in-house. Engineers apply it when iterating a BMS PCB carrier design, when generating shop drawings for a custom test jig, and when running quick FEA on a busbar to confirm thermal headroom under fault current.
