Fusion 360

Proprietary, web-based CAD/CAM software by Autodesk. [1]

Fusion announced that it will change available features for "Fusion 360 for personal use": export to STEP, SAT, and IGES will not be possible from 1st of October 2020. People from FreeCAD community suggest to export files to STEP files before 1st of October.

Some reaction FreeCAD community and Hackaday. This is a good lesson about using proprietary software and cloud services.
