摘要:随着计算机运算速度、图形处理能力及图形学理论的发展，CAD软件已经有了质的飞跃，CAD技术正在从原来简单的辅助绘图(Drafting)向成为真正能够辅助设计(Design)的工具发展，网络化、集成化、智能化和标准化已成为新一代CAD软件的重要特征，而三维建筑信息模型(BIM)正是实现以上目标的基础。PKPM通过核心三维数据模型，将建筑项目的各个环节连接起来，率先实现了信息数据化、数据模型化、模型通用化的BIM理念，进而实现了建筑模型数据在全寿命周期的充分利用。PKPM系统涵盖了规划、建筑、结构、设备以及算量造价、施工管理、乃至企业管理各个方面。在建筑全生命周期内，实现了建筑各个专业之间的信息充分互用，提高建筑信息的复用率，从而达到降低建筑成本，提高生产效率的目的。

Abstract: CAD software has been improved greatly by the developing of operational speed, graphics capability, and graphics theory in computers.CAD technology is developing from simply drafting to assistant design tools. BIM is the base of the next generation CAD software which the important features is networking, integration, intelligent and standardization.Using Building information model, PKPM series software realize the idea of digital information, data modeling and making general of building model through connecting each segment in construction projects, and achieve to fully utilizing the model data in the life cycle of building.PKPM series software cover many fields including planning, architecture, structure, facility, budgeting, construction and business management, take full advantage of data among each specialty in designing process, reduce the construction cost and improve efficiency.
