| 摘 要： | 产品信息建模是工程设计中各类产品信息通信，交换和共享的关键，工程产品信息模型要求具备统一，完备及动态的协同特征，文中针对工程设计的特点和工程产品的信息结构层次，通过“图元对象”概念的引入，图元对象粒度的建立和协同链接集成，在图元对象的内部关联和外部链接两个层次建立了工程产品CAD信息集成模型，最后在工程实现说明了该信息模型的合理性与有效性。

| Abstract: | Product info modeling is the key factor for communicating, exchanging and sharing of design info in AEC(architecture, engineering, construction). The info in AEC product needs to have cooperative characters including identical, complete and dynamic feature. According to the specific features of AEC industry and info levels of AEC product, concepts of drawing cell (DC), granularity of DC object (DCO) and collaborative links are introduced to realize the CAD info integration, which maps the geometrical and topological constraints of product info into inner\|correlation and outer\|hyperlink of DCO. Tests of experimental prototype system in engineering applications shows the rationality and validity of the ideas. |
