CAD (computer aided design) is a hardware and software system used in the development and documentation of real objects. It covers all activities in a design process, such as modeling, concept development and transfer to manufacturing. In the real estate industry, CAD is usually used in the field of architecture or civil engineering.
Due to an almost realistic representation, CAD projects help to convince potential buyers and tenants of a property or to illustrate planned conversion measures. The modeling can also contain information about the interior of a building, which is why they are also used in the field of interior design.
