Tinkercad runs entirely on Autodesk’s cloud servers. Your 10-year-old Celeron laptop will handle complex designs just as well as a gaming PC. The Windows 10 app acts as a polished viewer/controller, not a local render engine. No fans spinning up, no crashes.

Once you try to design parts with tolerances under 0.5mm (e.g., mechanical joints or threaded caps), you’ll feel the pain. Tinkercad snaps to a grid, and while you can turn snap off, it is notoriously finicky. Professionals will scream; beginners won't notice.

(Loses half a star for the lack of offline mode and basic precision limits, but earns full marks for what it promises: accessible, fun, 3D design for everyone).
