3D design engineering refers to the process of creating and designing three-dimensional models using computer-aided design (CAD) software and engineering principles. It involves the development of digital models that represent physical objects or systems, allowing engineers to visualize, analyze, and refine designs before they are physically produced.

3D design engineering has revolutionized the product development process, enabling faster prototyping, reduced errors, improved design visualization, and enhanced collaboration. It has applications in various industries, including automotive, aerospace, consumer electronics, industrial equipment, and architecture.
