Zachary Ventimiglia developed a dimension swap feature for the Floorset Editor in the SVSU-Capstone25/PLOT-FE repository, enabling users to interchange width and length for walls and fixtures through an X control and modal or direct input. He implemented interactive UI elements, such as pointer cursor changes on hover, and integrated the swap logic into the existing wall-building workflow, ensuring compatibility with current fixture values. Using Blazor, C#, and CSS, Zachary also addressed UI stability by reverting unintended changes in FloorsetEditor.razor.css and cleaning up unused styles, resulting in a more robust and maintainable front-end codebase.
