The hierarchical relationships among parts in a 3D assembly and among features in a feature-based part. Complex assemblies consist of subassemblies containing parts or possibly more subassemblies. Parts of feature-based CAD models consist of a base feature onto which additional features are applied. Features may themselves have dependent features.
