Abstract: At present, Plant Design Management System (PDMS) is one of the most important 3D design software in petrochemical field. It shows advanced engineering design, construction and management concepts. In engineering design, the core idea of the software is to center on process flow and establish a detailed 3D digital factory model by realizing multi-specialty real-time collaborative design. Taking several links of an engineering design project including data integration, model design and mutual delivery of information as example, this paper discusses the ways and methods of collaborative design among various specialties, introduces the relevant design modules of PDMS and other professional software that can realize data input and output with PDMS，and elaborates that the collaborative design is partly based on the summarized experience of practical engineering applications and partly based on the attempt and exploration of collaborative design among various specialties on the PDMS software platform

Key words: plant design management system/PDMS, collaborative design, digital factory
