Abstract. The article discusses the possibilities and efficiency of designing the creation of aircraft parts in 3D modeling using the automated system AutoCAD 2022. It is possible to design the external and internal layout of the aircraft, to determine in advance the structural-load diagram of the main components of the aircraft and to automatically coordinate it with the layout solutions. In conclusion, the article discusses the conclusions about the use of this software. This is an increase in the efficiency of engineers’ labor, the creation of high-quality design documentation, and development.

Key words: airplane, design, CAD, parametrical 3d model of an airplane, initial design matrix, layout.
