Introduction to Reverse Engineering

Reverse engineering is a process that involves measuring a physical object and reconstructing it as a 3D model to recover the design intent. The reasons for reverse engineering are multiple: to replace damaged components, to update obsolete parts, to fit new parts into a current assembly or environment, to generate new manufacturing plans 3D scanners are generally the preferred technology for extracting dimensional information and representing it as a point cloud or an automatic and instant mesh.

What is 3D scanning?

Laser 3D scanning is certainly the most common and used 3D scanning technique. Digitally capturing the shape of the object using laser light to get a digital representation of the real object. These 3D scanners are able to measure really fine details and capture free-form shapes to generate highly accurate point clouds.

This laser scanning technique is perfect for measurement and inspection of complex geometries. It allows getting measurements and data from where it is impractical with traditional methods!

A scanner using laser light is a little bit like a camera: it can only capture what is in its field of view. With this process, a laser dot or line is projected on an object from the device and a sensor measures the distance to the surface of this object.

By processing this data, it can be converted into a triangulated mesh, and then a CAD model.
