what is parametric modeling used for
Parametric is a term used to describe a dimensionâs ability to change the shape of model geometry as soon as the dimension value is modified. Feature-based is a term used to describe the various components of a model. For example, a part can consists of various types of features such as holes, grooves, fillets, and chamfers. A âfeatureâ is the basic unit of a parametric solid model. Parametric modelling uses the computer to design objects or systems that model component attributes with real world behaviour. Parametric models use feature-based, solid and surface modelling design tools to manipulate the system attributes. One of the most important features of parametric modelling is that attributes that are interlinked automatically change their features.
