Explain the meaning of "forward engineering" and "reverse engineering"

Forward engineering is carried out according to the normal path. Firstly, the product is positioned, such as the appearance, size and functional requirements of the product, and then the designer designs and manufactures the products that meet the requirements according to this positioning requirement.

Reverse engineering is to accurately measure the data of shape coordinate points according to the existing entities, and then construct the solid geometric model of the object according to the measured data points; Then, edit the solid model; It is an existing finished product, and then study how it is designed and manufactured. Through disassembly, analysis, exploration, testing and imitation, the development, design, development and debugging stages of the project are reproduced, and finally substitution and mass production are realized. Reverse engineering is mostly used for cottage high-tech products and weapons.
