2D and 3D CAD (Computer-Aided Design) are professional tools used to create accurate 2D drawings and detailed 3D models. These technologies enable efficient design development, editing, and standardization while ensuring consistency in technical documentation.

2D CAD focuses on precise drawings and specifications, while 3D CAD enhances visualization and allows early detection of design issues. Both support annotations, layer management, and industry standards, making them widely applicable in engineering, architecture, and manufacturing.

By using 2D and 3D CAD, organizations can improve documentation quality, reduce errors, enhance collaboration, and streamline development processes.
