In top-down assembly modeling, which action can be performed on geometry at the assembly level?

In top-down assembly modeling, one of the key advantages is that components can be designed and integrated into the assembly directly. When creating a new component, adding geometry at the assembly level allows for immediate referencing and relationships to be established with the existing components. This process ensures that the new component fits well within the overall design context from the very beginning, enabling a more cohesive and efficient design workflow.

This approach is particularly useful because it allows designers to factor in the assembly layout and spatial relationships right from the creation phase, minimizing the need for extensive modifications later. The ability to add new geometry directly at the assembly level is essential for maintaining the integrity and functionality of the assembly as a whole, which is a fundamental principle of top-down design methodology.
