嗨，HN，我有一台3D打印机，但我在CAD方面的能力很差。使用大型语言模型（LLMs）进行编码对我来说非常有效，因此我一直在尝试将类似的工作流程应用于CAD/建模。对于简单的功能性部件（夹具、支架、适配器、小型夹具），我可以使用LLM和OpenSCAD进行循环：它编写OpenSCAD代码，我进行编译/渲染，渲染几个视图，LLM“查看”这些图像，然后我们迭代直到看起来合适。这已经很有帮助，但很快就遇到了瓶颈。任何超出简单参数化原始体的内容都变得很痛苦（复杂几何形状、精确接口、装配、公差/配合等）。我对两件事很感兴趣。首先：你认为我们什么时候能够生成与专业水平相当的模型，类似于LLMs目前在编码方面所能做到的？其次：这种工作流程在实践中会是什么样子？它会主要保持参数化（OpenSCAD/约束），还是会更像是在SolidWorks/Fusion等工具中具有交互式“CAD副驾驶”的功能，可以通过截图+点击的方式编辑特征树？或者完全不同，比如文本转化为具有约束和检查的完整特征历史。如果你已经在做这个，今天哪些工具/工作流程能取得最佳效果，它们又在哪些方面存在不足？谢谢！

Hi HN,I have a 3D printer but I’m pretty bad at CAD. Using LLMs for coding has worked extremely well for me, so I’ve been trying to apply a similar workflow to CAD/modeling.For simple functional parts (jigs, brackets, adapters, small fixtures), I can use an LLM + OpenSCAD in a loop: it writes OpenSCAD, I compile/render, I render a few views, the LLM “looks” at the images, and we iterate until it looks right. This is already helpful, but it hits a ceiling quickly. Anything beyond simple parametric primitives becomes painful (complex geometry, precise interfaces, assemblies, tolerances/fit, etc.).I’m curious about two things. First: any intuition on when we’ll be able to generate models at a professional level, comparable to what LLMs can do for coding right now? Second: what will that workflow look like in practice? Will it stay mostly parametric (OpenSCAD / constraints), or will it look more like an interactive “CAD copilot” inside tools like SolidWorks/Fusion that can edit the feature tree via screenshot + click style interaction? Or something else entirely, like text turning into a full feature history with constraints and checks.If you’re already doing this, what tools/workflows are giving the best results today, and where do they fail?Thanks!

问HN：大型语言模型（LLMs）何时能够生成专业水平的CAD模型？
