Abstract: Plant Design Management System (PDMS) is a threedimensional (3D) design software of AVEVA from UK. The self improvement of the user is an important aspect for the development of PDMS. An embedded aided design software for checking supports and hangers is developed based on PDMS platform. The programmed load computation software for supports and hangers can be used to automatically check the load and output the optimal form of supports and hangers. In this way, the safety of supports and hangers design is improved, the construction cost is reduced, and the economic performance is enhanced.
