What is a key distinction between projected views and model views?

The key distinction that sets projected views apart is that they rely on an existing view to be created. In drawing practices, a projected view is typically generated from a parent view, such as a front or top view. This hierarchical relationship ensures that the projected view accurately reflects the geometry and details from the original view while maintaining a consistent scale and alignment.

By requiring a pre-existing view, projected views allow for a more organized and structured approach to documenting the 3D model, as they automatically include relevant dimensions and scaling consistent with the parent view. This connection aids in maintaining the integrity of the representation throughout the drafting process.

In contrast, model views can be created independently from any existing views, directly representing the 3D model itself. This fundamental difference is what defines the nature and usage of projected views in technical drawings.
