The Conference Service 3D Simulation Design Platform System is a 3D design software for planning and organizing conference events. It is divided into three major modules: conference seating arrangement, on-site conference setup, and micro-lessons on conference scenarios. It presents with 3D simulation micro-lessons, creative on-site design, and a 3D simulation training task system. In a 3D environment, it allows for overall on-site setup and seating arrangement for various types and themes of conferences. It fully utilizes students' creative design ideas and provides detailed explanations on conference types, composition, on-site services, welcome and registration services, conference living services, tea break services, seating arrangement, and on-site setup. Part of the content is viewed through 3D micro-lessons, and another part is trained through hands-on practical exercises, integrating learning, practice, and assessment to greatly meet the teaching requirements of conference service courses.
