3d modeling

Definition

3D modeling is the process of creating a three-dimensional representation of a physical object or surface using specialized software. This technique allows engineers and designers to visualize complex structures, analyze their behavior under various conditions, and facilitate communication among project stakeholders. In fields like earthquake engineering, 3D modeling plays a crucial role in simulating the structural response to seismic forces, enhancing the understanding of performance and safety.
