The so-called reverse engineering technology is to carry out 3D scanning and data collection on the original shape of the object, and construct the 3D model with the same shape and structure through the process of data processing and 3D reconstruction. Then, in the original copy or in the original on the basis of redesign to achieve innovation. Therefore, reverse engineering is not a simple process of 3D scanning and replication. The purpose of reverse engineering is to obtain point cloud with physical objects, and carry out optimization design and innovative design based on point cloud. Of course, reverse design is not mysterious. It is closely related to our life. The upgrade and transformation of bicycles in daily life and the more flawless streamline of cars are all inseparable from reverse design.

So when do you reverse engineer? We find that reverse engineering is mainly applied in the following aspects.

1. Obtain a parametric model that can be edited by 3D software to facilitate material processing by CNC machine tools and other machining enterprises.

2. In order to obtain more reasonable data structure, such as the improvement of automobile contour streamline modeling and turbine blade, etc. Through reverse engineering design, the data obtained by scanning are modified to achieve the purpose of optimization and innovation.

3. In order to obtain two-dimensional drawings. In general, computer companies pay more attention to the acquisition of two-dimensional drawings. Reverse engineering can obtain the three-dimensional model of the object through the reverse design of scanning data, and the two-dimensional drawings of any section of the object can be obtained conveniently and quickly in the drawing software.
