In order to solve the problem that the assembly status information feedback is not intuitive in the actual production site

 to facilitate the management and avoid errors

 and to ensure the realization of the progress goal

 this paper proposes the use of CATIA Composer from the perspective of 3D visual display of assembly progress. The method of building a 3D display platform for assembly status of aircraft components by composer software is studied. The acquisition logic of assembly status of parts based on 3D AO and MES system is studied. The information model of assembly status of components is established. The display method of 3D model driven by assembly status of parts is put forward. The display process of assembly progress of aircraft components based on real-time production information is described. The central wing assembly workshop is used as an example to verify the feasibility of the method.
