What a C.A.D program?

A C.A.D. program, or Computer-Aided Design program, is software used by architects, engineers, and designers to create precise drawings and models. It allows users to develop 2D and 3D representations of physical objects or structures, facilitating design visualization and modification. C.A.D. programs enhance productivity, improve accuracy, and streamline the design process by providing tools for drafting, modeling, and simulation. Common examples include AutoCAD, SolidWorks, and SketchUp.
