Solid modeling is a computer-aided design (CAD) technique used to create a three-dimensional representation of an object. This method allows designers 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 engineering, architecture, and product design. One of the key benefits of solid modeling is its ability to provide precise measurements and details, which are essential for manufacturing and prototyping. Solid models can also be easily modified, allowing for quick adjustments and iterations during the design process. This flexibility makes solid modeling a valuable tool for designers and engineers alike.
