With the development of information technology, thermal power plants have gradually carried out the full 3D digital design, various manufacturers have proposed the corresponding full 3D digital design scheme combined with the unit design software application situation, which has made some progress but still insufficient. In the digital collaborative design of thermal power plants, the author′s company has the problems that civil engineering specialty is not covered by 3D digital design, the degree of workflow collaboration is low and the design model has information islands. This paper combines the data linking software of Revit, structural calculation software, and PDMS developed by the company to open up the data link between the three, and proposes a set of digital collaborative design solutions of moving forward civil engineering design to the upstream of collaborative design with Revit software as the core. It improves the degree of the company′s civil 3D digital design, effectively ensures the consistency of data structure design, and improves the efficiency of collaborative design at the same time.
