Feature-Based Modeling is a design approach used in computer-aided design (CAD) that focuses on defining the geometry of a model through its features. Features are specific attributes or operations, such as holes, extrusions, or fillets, that represent the functional aspects of a part. This method allows designers to create complex shapes by manipulating these features rather than just working with raw geometry. This modeling technique enhances collaboration and efficiency in the design process. By using features, engineers can easily modify designs, as changes to one feature automatically update related components. This adaptability is particularly beneficial in industries like automotive and aerospace, where precision and flexibility are crucial.
