    • A method for processing a design model generated by a computer aided design system includes accessing model data that includes separately stored data documents detailing construction of the design model from a collection of components, processing the model data to generate image elements representing a projected view of the design model and to generate tag data associating each of the image elements with at least one of the of components and storing the first image elements and the first tag data in a drawing document. Supplementary data can be added to the drawing without the need for the external components to be available on disk or in memory. An updated drawing document can be generated following a change to one of the components. Generating an updated drawing document includes generating tag data that identifies matchings between the original and changed model components. Annotations and other supplementary data can be attached to image elements and stored in drawing documents. These annotations can be retained when the updated drawing document is produced. Methods of the invention can be implemented in software in a computer system.
    • 一种用于处理由计算机辅助设计系统生成的设计模型的方法包括访问模型数据,该模型数据包括分开存储的数据文件,其中详细描述了从组件集合中设计模型的构造,处理模型数据以生成表示投影视图的图像元素 并且生成将每个图像元素与组件中的至少一个相关联并且将第一图像元素和第一标签数据存储在绘图文档中的标签数据。 补充数据可以添加到图形中,而不需要外部组件在磁盘或内存中可用。 在更改其中一个组件后,可以生成更新的绘图文档。 生成更新的绘图文档包括生成识别原始组件和已更改模型组件之间的匹配的标签数据。 注释和其他补充数据可以附加到图像元素并存储在绘图文档中。 当生成更新的绘图文档时,可以保留这些注释。 本发明的方法可以在计算机系统中的软件中实现。

    • Creating a reference to data used to construct a computer-aided design model includes storing model data with tracking data, where the tracking data identifies the model data. A reference is created and the tracking data is associated with the reference to enable the reference to refer to the model data. A modeling operation is executed, which retrieves the tracking data associated with the reference, traverses a data structure defining the computer-aided design model while attempting to match the tracking data associated with the reference to the tracking data stored with the model data, and returns geometric data stored in the model data.
    • 创建对用于构建计算机辅助设计模型的数据的引用包括使用跟踪数据存储模型数据,跟踪数据标识模型数据。 创建一个引用,跟踪数据与引用相关联,以使参考引用模型数据。 执行建模操作,其检索与参考相关联的跟踪数据,遍历定义计算机辅助设计模型的数据结构,同时尝试将与参考相关联的跟踪数据与存储有模型数据的跟踪数据相匹配,并返回 几何数据存储在模型数据中。
