Reverse engineering is the process of reproducing a part by extracting surfaces or sketches from a scanned point cloud or mesh to create a CAD model of the part. The product reflects how the part was to be designed originally. Creating a 3D CAD model from a 2D drawing to reflect design intent is also another form of reverse engineering. Reverse engineering is becoming a more popular method of creating a 3D model of a part without existing CAD files. This process has saved lots of individuals and companies’ time, cost and increased quality on design processes and time to market.
A 3D scanner can be used to scan/analyze a real-world object or environment to collect data on its shape and possibly its appearance (color or/and texture). The collected data can then be used to construct a digital 3D model.
