3D modeling

Definition

3D modeling is the process of creating a three-dimensional representation of a physical object or environment using specialized software. This technique is crucial in engineering and design, as it allows for the visualization, manipulation, and analysis of complex structures before they are built. By converting ideas into detailed digital formats, 3D modeling enhances communication and accuracy in the design process.
