Astra 把文字需求变成五速变速箱 3D 模型
OpenAI 称 Astra 在 FreeCAD 里建模、用 Blender 做齿轮与轴动画，适合早期设计评审，但未验证真实负载下能否工作。
GPT-6 ASTRA TURNED A TEXT BRIEF INTO A FIVE-SPEED GEARBOX MODEL The gearbox in this video started as a written brief. OpenAI says Astra built the concept in FreeCAD, then used Blender to animate the gears and shafts. Watch the teal highlights as the animation changes gears. For an early design review, that gives you something concrete to put in front of a colleague or client. Pause on one stage, inspect the assembly, and discuss what needs changing. OpenAI says the concept can be refined through follow-up feedback. I’d start with the technical documents nobody wants to read: turn one mechanism into a model a client or student can follow. The clip doesn’t establish that this gearbox would work under real loads. But turning an idea into a moving explanation is already a useful task to hand to an agent.
