The Library Explorer opens. If you do not have a vehicle library loaded, all you will see is a bookshelf icon with the word Pool beside it. This represents the pool of vehicles used in and saved with your drawing.
The buttons at the top are mutually exclusive and allow you to group the vehicles by Vehicle Group (default), Category, Classification, Type or Ungrouped. There is also an option to display all vehicles for all libraries together.
The arrow on the header bar allows you to list the data in ascending or descending alphanumeric order. You can click on the arrow to change the order, or click on another column header to sort by another item of data.
You can add or remove data from the display by clicking the Insert/Remove Columns button.
You can click the Vehicle Diagram button to switch the vehicle diagram on and off.
