Which area displays model features in the part environment?

The area that displays model features in the part environment is the Pathfinder. The Pathfinder organizes and shows all the components, parts, and features in the assembly and part environments in a clear, navigable structure. This includes features like extrusions, cuts, patterns, and more, allowing users to easily manage and access their model's features.

Using the Pathfinder provides a comprehensive overview of the design structure, facilitating quick edits and modifications. This area enhances the workflow, enabling designers to keep track of all the elements within their models efficiently. It serves as a centralized control hub for interactions with the various features of the model, making it vital for effective part and assembly design management.

The other options, while they may relate to parts of the modeling interface, do not primarily serve the function of displaying model features as directly as the Pathfinder does.
