The developed algorithm of indirect parametrization of 3d model of a typical part by means of parametrization of its longitudinal section is presented in the work. Controlling the shape of 3d objects by parameterizing their 2d cross-sections allows, using AutoCAD CAD, to create variants of electronic models of parts, the same type in geometry and different in size characteristics. This saves resources that are spent on design work. The proposed algorithm for creating parameterized 3d models in the CAD environment AutoCAD can be used in engineering practice. Currently, methodological developments have been introduced into the educational process at the Kyiv Polytechnic Institute named after Igor Sikorsky when teaching the course "Engineering and Computer Graphics".
