In order to improve the guidance of the drawing to production and achieve the correspondence between MBOM and the drawings, a method of digital design for generalpurpose aircraft aimed at manufacturing has been researched while reducing the conflicts of each professional field during detailed design at the same time. The general scheme was designed combined with production process, and the general parameters were defined at this stage. The structure of 3D model was based on assembly process and the skeleton was created based on the demandoriented collaborative design platform. Thus the 3D models was designed. The test on a real type of aircraft shows that based on the 3D modeling, the conflicts during design were solved immediately, the designs between several stations were associated immediately, the production was guided by drawings directly and the development period of the aircraft was shortened significantly.
