Shapr3d tutorial beginner4/22/2023 ![]() Instead, they think about features, like faces and edges, that correspond to the model’s physical entities. In fact, design professionals rarely think along the lines of these primitives whenever they are creating a part. Dealing with these primitives is less desirable, especially when designing complex parts. You see, a conventional 3D model comprises primitive geometric entities such as curves and points and solid primitives such as cylinders, cones, spheres, boxes, and wedges. This paradigm is sometimes also known as feature-based parametric modeling. Relations within the sketch profile (sketch relations). ![]() Parametric relationship between dimensions.The relationship between the base block (unmodified block or parent) and any newly introduced entity (child), also known as a parent-child relationship.Generally, the design intent in parametric modeling is captured by: After all, all the dimensions have a predefined relationship. Thus, the entire model will be automatically modified or rebuilt whenever one or more dimension values are changed. Parametric modeling is a design paradigm that involves stipulating dimensions that define the geometry of a part and subsequently establishing and outlining the relations between the dimensions both across and within the part.
