Reverse engineering is the process of product design technology reproduction, that is, reverse analysis and Research on the project standard products to infer and deduce the processing flow and organization mode of product design elements, such as structure, functional characteristics and technical specifications, so as to produce products with similar but different functions.

Reverse engineering refers to the process of measuring the real object or model with certain measurement means, reconstructing the CAD model of the real object through three-dimensional geometric modeling method according to the measurement data, so as to realize product design and manufacturing. Different from the traditional design and manufacturing methods, reverse engineering is to accurately and quickly measure the surface data or contour of the sample by using a three-dimensional scanning measuring instrument without design drawings or incomplete drawings, carry out point data processing, surface creation, three-dimensional solid model reconstruction, and then print the model through a 3D printer.
