这太明显了，以至于我们以为我们已经列出了 OpenSCAD 这个问题已经存在多年了。现在错误终于得到了纠正。

最高效的程序化 3D 实体建模器：你编写代码，它就能转换成实体 3D 模型。

大社区、大历史、多应用、免费。许多人都制作了参数模型，因此您只需调整一个或几个参数，它就会自动适应（典型案例：齿轮，您只需给出模数、宽度......就能得到精确的 3D 模型）。

It is one of the REALLY rare tool that we promote that 必须 be installed as it is not online. But it worth it.

提示1： 我们还在该目录中列出了其在线分叉，即"OpenSCAD Playground以及一个在线衍生产品JSCAD，两者各有优势。这里只是为了测试其原理，因为它们尚未实现所有功能。

专业提示2： 由于基于文本的程序化 openSCAD 编码已经广为人知多年，因此您可以让大多数 AI（包括我们免费的 AI）GPT 仅凭文本提示生成 SCAD 3D 代码。只需文本输入即可生成 3D 模型！这对于复杂的重复几何图形、遵循曲线或规则的几何图形，以及某些科学数据尤其有用，而标准桌面软件则难以胜任。计算机辅助设计编辑们不太务实。

学科： 机械工程、3D打印、产品设计、机器人技术。

OpenSCAD Programmatic Solid 3D CAD Modeller compared with SolidWorks, Autodesk Inventor and Autodesk Fusion
OpenSCAD 程序化实体 3D CAD 建模器	SolidWorks	Autodesk Inventor	Autodesk Fusion
Modelling approach: The project describes itself as not an interactive modeller. A script defines the object using constructive solid geometry and extrusion of 2D outlines, and the program compiles it to a solid. Parameter-driven designs follow naturally, since every size is a variable.	Modelling approach: Interactive part and assembly modelling with 2D drawings. The Professional plan adds a CAD library, rendering and cost estimation, and Premium adds simulation and routing.	Modelling approach: Interactive modelling that mixes parametric, direct, freeform and rules-based design. It also covers sheet metal, tube and pipe, frame design and iLogic automation, which OpenSCAD does not offer.	Modelling approach: Interactive CAD in a graphical interface with CAM in the same product. The personal plan has basic CAM only.
平台和安装： Installed locally. Packages exist for Windows, macOS, Linux (AppImage, Snap, Flathub), BSD and Docker, and a WebAssembly build exists. Nightly snapshots can enable the Manifold geometry engine, listed as a large speed gain.	平台和安装： Installed on the local computer and deployed from the cloud. Work Offline mode lasts up to 30 consecutive days.	平台和安装： The vendor page states that Inventor runs on Microsoft Windows and names no other system.	平台和安装： Desktop application. The personal use plan allows one user and single-user data management.
Inputs, outputs and formats: The project page states that it reads and creates STL and OFF models, and uses DXF for 2D outlines, which can also supply parameters. It produces meshes for printing, not the exchange formats of mechanical CAD suites.			Inputs, outputs and formats: The free personal plan has limited file import and export and no commercial data translators.
许可证和费用： Free software under the GNU General Public License version 2. No account, no seat management.	许可证和费用： Subscription. The Standard plan is a per-seat licence on the vendor store.	许可证和费用： Commercial subscription with monthly, annual and 3-year billing and a 30-day free trial. Amounts are on the vendor page.	许可证和费用： Free for non-commercial personal use only. Client work, consulting or product sales need a commercial subscription.
Level of expertise required: Comfort with programming concepts and geometric reasoning. Particularly suited to engineers who already script, and to parts defined by equations or data.	Level of expertise required: Professional CAD training typical for mechanical design offices.	Level of expertise required: Professional CAD training, plus iLogic if rules-based automation is used.	Level of expertise required: CAD training for design work. Fewer specialised functions than the commercial edition.
何时选择它： Choose it for parametric parts, repeated or rule-based geometry, and models kept as plain text in version control. Choose a commercial suite for assemblies, drawings and neutral CAD exchange.	何时选择它： Choose it for company workflows needing drawings, revision management and vendor support.	何时选择它： Choose it for Windows-based mechanical design with sheet metal, piping and automation needs.	何时选择它： Choose it for hobby projects needing CAD and CAM in one tool at no cost.
