Features and Parts
All models that you build contain the following fundamental anatomical attributes:
Features—Individual geometry created one at a time. Features include datums, extrusions, holes, rounds, chamfers, surface features, cuts, patterns, sweeps, and so on. You can have multiple features in a part.
Parts—Collection of geometric features that define the geometric entity called the part. Parts are referred to as components in an assembly. You can have multiple components in an assembly.
Assemblies—Collection of components assembled together to create the model. You can have multiple assemblies and subassemblies in a hierarchical order according to their relationships with other assemblies and the master assembly.
