Which tool can an architectural designer use to edit multiple walls across different design options?

The tool that allows an architectural designer to edit multiple walls across different design options is called "Pick to Edit." This tool is specifically designed to facilitate the selection of multiple elements within a Revit project, making it easier to apply changes across various design options.

When an architectural designer wishes to modify walls that are part of different design scenarios, utilizing "Pick to Edit" enables them to efficiently select all relevant wall elements simultaneously. This streamlines the modification process and ensures that any alterations are consistent across the selected options, thus enhancing the method of comparison and decision-making in the design phase.

This capability is critical in an architectural design context where multiple versions or iterations of a project may be considered. The other tools listed do not provide the same direct functionality for selecting and editing multiple elements across different design options, making this choice particularly valuable in the workflow of architectural designers.
