Parametric Modeling is a design approach that uses parameters or variables to define the geometry and behavior of a model. This allows designers to create flexible and adaptable designs, where changes to one part of the model automatically update related components. It is commonly used in fields like architecture, engineering, and product design. In parametric modeling, parameters can include dimensions, angles, and other attributes that influence the overall shape and structure. This method enhances efficiency, as designers can quickly explore different design options and make adjustments without starting from scratch. Popular software tools for parametric modeling include AutoCAD, SolidWorks, and Rhinoceros.
