3D CAD (Computer Aided Design) is a design technology that uses three-dimensional graphics. This technology is used in the manufacturing and construction industries to interactively review and revise designs and create proposals.

Unlike 2D CAD, 3D CAD software allows designers to design spaces in three dimensions. This allows for various angles of view and the ability to rotate the model for review. 3D CAD software can also simulate machining procedures and is used to study and improve manufacturing processes.

3D CAD technology has evolved significantly compared to the past, and it is now possible to realize manufacturing and architecture using 3D printers and laser cutters, etc. 3D CAD is expected to continue to play an important role in the future as it contributes to efficient design work, development of high-quality products, and high-precision manufacturing. 3D CAD is expected to continue to play an important role in the future.
