When designing new products or adapting existing parts, engineers and designers like to use 3D scanners as a starting point for digitizing clay models or measuring physical objects in order to reconstruct their 3D models and integrate them into their designs.īut the role of 3D scanners does not stop at the design stage. The process of converting a physical object into a virtual 3D model is called reverse engineering, and the bridge between worlds can be crossed thanks to 3D scanning. Thus, a bridge between the physical and the digital world is necessary to transition from an existing object to a CAD model. Obsolete parts and damaged components must not be forgotten, as they often need to be updated, replaced, or fitted into a new assembly or environment. New parts can be designed entirely and directly in CAD software or they can be hand-sculpted using clay or other materials. But how do we get into this process, knowing that, of course, we cannot insert a physical object into a computer? The CAD process, however, is a closed digital procedure, meaning that all of the functions happen digitally inside the computer.

CAD software enables designers and engineers to model shapes and add features with the ultimate goal of producing parts.

Computer-aided design (CAD) is defined as the use of computers to assist in the creation, modification, or optimization of a design.
