For example, integrating Excel’s form controls with platforms like a room planner can streamline your workflow—allowing you to track design elements, layouts, and even generate instant material lists for any room project. Incorporating such digital tools enhances efficiency and precision, a practice I adopt regularly in both large and small design projects.Tips 1:You can toggle Design Mode off once you finish editing controls to ensure that any interactive VBA code or macros assigned to the controls will start functioning as intended.
