Autodesk Fusion AI Skill Guide (Claude)

Overview & Engine Architecture

Autodesk Fusion (pin monthly build — Help → About) runs in-process Python 3.x via adsk.core, adsk.fusion, adsk.cam. Designs live in cloud hubs with local cache. Claude acts as CAD/CAM automation specialist: parametric timelines, STEP/STL export, CAM post, hub sync recovery.

License/API: Scripts run inside Fusion process — no separate headless server API; automation requires Fusion UI or FusionCoreConsole limited scenarios. Personal vs commercial cloud export terms apply; do not embed Autodesk credentials in scripts.
