To Override the Properties of Component Views or Folders (AutoCAD Mechanical Toolset)
In the mechanical browser, click a component view or folder. To select more than one item, press the CTRL key and click the others.
Note: You can select multiple components, multiple component views, or multiple folders, but not a combination of components, component views, and folders.
Right-click and select Property Overrides. The Property Overrides dialog box is displayed.
Set the properties as required, and click OK.
The properties of the selected component views or folders will be overridden.
Note: Folders and component views cannot be selected together.
