The three-dimensional (3D) design data employed in a process plant construction project are generated during both the basic design and detailed design stages and are used for various purposes throughout the life cycle of the project. After the design stage, 3D design data are converted to a lightweight 3D format and utilized to support procurement, construction, and audit work in a collaborative project management system. However, significant time and cost are incurred when separate interfaces to convert design data are developed for each plant 3D computer-aided design (CAD) system. As an alternative, a method exists to integrate an interface using a neutral model. After translating the 3D input design data for the plant 3D CAD system to a neutral format, this study proposes an interface for use in collaborative project management by converting the data into a lightweight 3D model. In addition, detailed techniques for implementing the proposed interface are described. To verify the validity of the proposed neutral model-based 3D design data interface, translation, inspection, and lightweighting experiments are performed using 3D design data for a synthesized natural gas production plant project.

基于中性模型的3D设计接口以支持过程工厂行业中的协作项目管理

加工厂建设项目中使用的三维（3D）设计数据是在基本设计阶段和详细设计阶段生成的，并在项目的整个生命周期中用于各种目的。在设计阶段之后，将3D设计数据转换为轻量级3D格式，并用于在协作项目管理系统中支持采购，施工和审核工作。但是，为每个工厂3D计算机辅助设计（CAD）系统开发用于转换设计数据的单独界面时，会花费大量时间和成本。作为替代，存在一种使用中立模型来集成接口的方法。将工厂3D CAD系统的3D输入设计数据转换为中性格式后，通过将数据转换为轻量级3D模型，本研究提出了用于协作项目管理的界面。另外，描述了用于实现所提出的接口的详细技术。为了验证提议的基于中立模型的3D设计数据接口的有效性，使用3D设计数据对合成天然气生产厂项目进行了平移，检查和轻量化实验。
