CAD Software

Definition

CAD software, or Computer-Aided Design software, is a technology used by engineers, architects, and designers to create precision drawings or technical illustrations. This type of software allows users to design in both 2D and 3D formats, facilitating the modeling of complex geometries and enabling the visualization of designs before they are manufactured. In the context of 3D printing, CAD software is essential as it generates the digital files that guide printers to produce physical objects.
