A model is the graphical representation of a parametric part. In Content Builder, a model consists of various features that have specific relationships to each other and that define the behavior of the parametric part. Some features require that you create simple shapes or points, while others require an extrusion or path. Some represent visible geometry, and some help you to position geometry precisely on a part. You can modify features to refine and improve your parts over time. You change features by modifying their size and shape or by flipping or moving them. To effectively model a parametric part, it is important to understand how each feature relates to the other features of m odeling.
The following illustration shows the features that make up the model. Arrows indicate the direction of the relationship between features. For example, modifying geometry affects a profile, which affects a modifier, and so on.
The following sections introduce the features of modeling. Refer to this illustration as you learn more about each feature to help you understand the relationships between features.
