所需的时间，在插件开发 期间删除构建 KiCad 的要求极大地提高了工作效率。 插件最初是为 3D 模型查看器开发的，因此可以支持更多类型的 3D 模型，而 无需对支持的每种新模型类型的 KiCad 源进行重大更改。 插件框架后来被推 广，以便将来开发人员可以创建不同类型的插件。 目前，只有 3D 插件在 KiCad 中实现，但可以想象最终将开发 PCB 插件，以使用户能够实现数据导 入器和导出器。 插件分为插件类，因为每个插件都解决了特定域中的问题，因此需要该域独有 的接口。 例如，3D 模型插件从文件加载 3D 模型数据并将该数据转换为可由 3D 查看器显示的格式。 PCB 导入/导出插件将获取 PCB 数据并导出为其他电 气或机械数据格式，或将外部格式转换为 KiCad PCB。 目前只开发了 3D 插件 类，它将成为本文档的重点。 实现插件类需要在 KiCad 源代码树中创建代码来管理插件代码的加载。在 ‘plugins/ldr/3d/pluginldr3D.h’ 声明了 3D 插件类的加载器。加载器负 责加载给定的插件并使其功能可用于 KiCad。插件加载器的每个实例代表一个 实际的插件实现，并充当 KiCad 和插件功能之间的透明桥梁。加载器不是 KiCad 中支持插件所需的唯一代码：我们还需要代码来发现插件和代码，以通 过插件加载器调用插件的功能。在 3D 插件的情况下，发现和调用功能都包含 在 S3D_CACHE

Plugins were initially developed for the 3D model viewer to make it possible to support more types of 3D models without requiring major changes to the KiCad source for each new generalized so that in the future developers can create different classes of plugins. Currently only 3D plugins are implemented within KiCad but it is envisioned that a PCB plugin will eventually be developed interface unique to that domain. For example, the 3D model plugins load 3D model data from files and translate that data into a format which can be displayed by the 3D viewer. A PCB Import/Export plugin would take
