Assembly information model is an important part of the product information model , which supports products from the overall design to the part design and the parallel design , provide sources of information as well as product design the subsequent assembly automation and assembly process planning , and design analysis and evaluation , shorten the product development cycle , reduce development costs has a great role , and has a wide range of applications in the field of CAD / CAM / CAPP . For product assembly process digitized expression describes the product assembly information model development background , connotation , and domestic and foreign research status quo ; related theory and the means of achieving ; three-dimensional digital model for the aircraft structure , the use of CATIA secondary development platform based on CATIA environment CAA and the C language , by batch ( background ) and interaction ( foreground) in two ways to establish the the airplane structure of virtual assembly model . A three-dimensional digital model of the structure of the aircraft , for example , the use of interactive and batch processing are two ways to extract the name of its layers , type , mass , center of gravity , volume , rotational inertia , part material , the same number of products , space transformation matrix , constraints relations and sports institutions to construct aircraft structures virtual assembly model , the model created to meet the information requirements of the aircraft structure assembly .
