Solid modeling is a computer graphics technique used to create a three-dimensional representation of an object. It allows designers and engineers to visualize and manipulate the shape, size, and features of an object in a virtual environment. Solid models are defined by their volume and can be used for various applications, including product design, simulation, and manufacturing. This technique is commonly employed in computer-aided design (CAD) software, which provides tools for creating and editing solid models. Solid modeling can represent complex geometries and is essential in industries such as automotive, aerospace, and architecture, where precise specifications are crucial for production and analysis.
