I would like to swap a number of DCs at one go, and checking the help…I should be able to
"Use the Swap Component menu item to swap the currently selected component with another component. For example, use this option to swap all windows of a specific type or manufacturer with windows of another type or manufacturer.
To swap out a series of components:
Select the dynamic components you want to replace. The components are highlighted in the drawing window.
Context-click on one component. The context menu is displayed.
Select Dynamic Components > Swap Component. The Select a SKP dialog box is displayed.
Select the SketchUp file containing the Dynamic Component to replace the currently selected components.
Click the Open button. The new Dynamic Component replaces the previously selected Dynamic Components."
this option is not available, ( I am using a windows platform) I can only change one DC at a time
