What is the function of the Paintbrush tool in Revit?

The Paintbrush tool in Revit serves the specific purpose of copying properties from one element to another. When you select an element and then click on the Paintbrush tool, you can apply the properties of the selected element—such as materials, finishes, and other attributes—to another element. This tool is invaluable for maintaining consistency across similar elements in a design by easily transferring specific styles or definitions without needing to manually adjust each one.

The other options represent functionalities that are distinct from what the Paintbrush tool offers. Setting the visibility of elements is managed through visibility settings and categorization, hiding elements in the view involves using the visibility/graphics settings or the hide tool, and applying view filters is done through the view properties and filter settings. Each of these functions serves different purposes in the overall workflow within Revit, distinguishing them clearly from the property-copying capability of the Paintbrush.
