JSCAD（原名 openJSCAD）是另一个在线衍生产品。 OpenSCAD 三维实体程序建模器。
我们提供给她的链接是 JSCAD 最完整的克隆实现之一，具有各种辅助工具、文档和格式导入（STL、DXF、X3D §）。
源代码可在 GitHub 上找到：https://github.com/jscad/OpenJSCAD.org，其中包括标准版、网页版和桌面版。
提示1： 文档：
技巧二： 该目录中还可以找到在线的“原始”openSCAD 版本，它与桌面版 openSCAD 具有更高的兼容性，但根据我们的经验，如果不需要兼容性，则实用性较低。

|---|---|---|---|
| Modelling approach: Models are written as JavaScript code and rendered in the browser. The geometry is parametric, so changing a variable regenerates the part. | Modelling approach: Models are written in its own scripting language and rendered by a desktop program. It is described as a programmers solid 3D CAD modeller. | Modelling approach: A cloud-based CAD application where features are drawn and edited with a graphical interface. | Modelling approach: A graphical CAD package, with a browser-based variant (xDesign) and desktop licences. |
| 文件格式： The openjscad.com mirror imports and exports JSCAD, STL, AMF, DXF and SVG (all but JSCAD marked experimental). It exports X3D and imports OpenSCAD .scad files. | 文件格式： The page consulted does not list formats. | 文件格式： The personal licence has fewer supported import and export file types than the paid version. | |
| 许可证和费用： Open source under the MIT licence, free to use online, offline and from the command line. | 许可证和费用： Free software, available for Linux, Windows and Mac OS X. | 许可证和费用： The personal licence is for non-commercial projects below a small annual revenue threshold and excludes company use. Commercial use needs a paid subscription. | 许可证和费用： Design licences are term-based (yearly or quarterly) online, and resellers can sell perpetual licences. A free trial is available. |
| 地位： The openjscad.com page identifies itself as a JSCAD v1 mirror provided by BuildBee. The jscad.app site presents the library as the JSCAD modeling package. | 地位： Listed as active software with tutorial and library pages. | 地位： Active as a product, with personal and full subscriptions. | 地位： Active as a product, sold by term or through resellers. |
| When to choose: Choose it for quick parametric parts without installation, or when the model must be generated by JavaScript code. | When to choose: Choose it for scripted solid models in a desktop program, and for compatibility with .scad libraries. | When to choose: Choose it for free-form mechanical design with CAM and electronics, if the personal licence conditions are met. | When to choose: Choose it when production drawings and a commercial design workflow are required. |
