中文摘要：

建筑协同设计是促进勘察设计企业信息化建设的关键因素，而CAD专业标准的建立是实施建筑协同设计的前提和基础。由此，论文针对建筑CAD专业标准进行了系统性的研究，阐述了国内建筑CAD专业标准的发展与现状，指出其中存在的各种问题，并结合上海华东发展城建集团在推广建筑协同设计平台过程中成功应用CAD专业标准的案例，给出了具体的解决方法。最后对cAD专业标准在建筑协同设计中的应用做出了总结，并对未来基于BIM的建筑协同设计平台进行了展望。

英文摘要：

Building collaborative design is the key factor of information construction for survey and engineering design enterprises, and the establishment of CAD standard is the premise and basis of building collaborative design. Thus, the paper carries out a systemic research on CAD standards, firstly describes the development and the present situation of domestic CAD standards, then points out some existing problems and gives out the solutions in detail with a practical case of the implementation of CAD standards in Shanghai ECUC Group. Finally, the application of CAD standards in building collaborative design is summarized together with further development of BIM-based building collaborative design platform.
