摘要:通过对传统作业指导书和3D作业指导书研究现状的分析，研发了一个基于BIM技术的3D作业指导书系统，该系统结合传统作业指导书，以技术指标、操作要点、资源配置等为核心，以工艺流程为主线，BIM模型为载体。系统由基础数据库、编辑客户端和浏览客户端构成：基础数据由BIM模型和文档等组成，存储于云平台；编辑客户端实现基础数据的导入、数据间的关联、3D作业指导书审核、发布等功能；浏览客户端进行3D作业指导书三维可视化查看。通过研发的系统，实现了作业指导书移动化办公和可视化指导现场施工，同时形成3D作业指导书知识库，使作业指导书更直观和便捷。

Abstract: Based on the situation analysis of the traditional job instruction and 3D job instruction, this paper develops a BIM-based 3D instruction system, which combining with the traditional job instruction, takes the technical index, the key points of operation, and resource allocation as the core, the process flow as the main line, and the BIM model as the carrier.The system consists of basic databases, editing clients and browsing clients. The basic data is composed of BIM models and documents, which are stored in the cloud platform.Through editing clients can implement the import of basic data, the correlation between data, the audit and release of 3D job instruction, and etc. Browsing client can be used for the 3D visualization of the job instruction. The system developed in this paper enables mobile office and visual guidance on site construction of the job instruction, and forms aknowledge library of 3D job instruction, making the instruction more intuitive and convenient.
