Abstract

Building information modeling (BIM) of mechanical, electrical, and plumbing (MEP) systems is essential for building facility management. Computer-aided-design (CAD) data are detailed sources for MEP BIM modeling. However, existing methods for MEP BIM are complex, leading to heavy reliance on manual intervention. This paper addresses this challenge by proposing an approach for generating MEP BIM models from CAD data. Graph structures are introduced to represent MEP systems, and multiple graph structures converted from CAD drawings are utilized to match pipeline components and aggregate dispersed information across various drawings. Based on the integrated pipeline graph, missing information is inferred and completed considering the relationships between components, ensuring detailed and accurate modeling results. Experiments on an actual factory case demonstrate the reliability and efficiency of this approach. This paper contributes to the MEP BIM theory by providing a perspective on interpreting MEP CAD data and a robust technical route of CAD-to-BIM conversion for MEP systems.

使用多图图形集成从CAD数据自动生成MEP系统的BIM

机械、电气和管道（MEP）系统的建筑信息建模（BIM）对于建筑设施管理至关重要。计算机辅助设计（CAD）数据是MEP BIM建模的详细来源。然而，现有的MEP BIM方法复杂，导致严重依赖人工干预。本文通过提出一种从CAD数据生成MEP BIM模型的方法来解决这一挑战。引入图形结构来表示MEP系统，并利用从CAD图纸转换而来的多个图形结构来匹配管道部件，并将分散的信息聚合在各个图纸上。在集成管道图的基础上，考虑组件之间的关系，推断和补充缺失的信息，保证建模结果的详细和准确。通过实际工厂实例验证了该方法的可靠性和有效性。本文为MEP BIM理论提供了解释MEP CAD数据的视角，并为MEP系统提供了CAD到BIM转换的可靠技术路线。
