The Toolbox contains all standard class objects of the Class Library. To build up simulation models, you first create new Frames. Then you use the Toolbox to insert objects into Frames by left-clicking their icon and left- clicking in the desired Frame. To insert multiple copies of an object, hold down Ctrl and click the left mouse button in the Frame.
The Toolbox is divided into different basic categories such as Material Flow, Resources, Information Flow, User Interface and Tools matching the folders in the Class Library.
You can customize the Toolbox, you can add new toolbars and then add objects to these toolbars. To do this, right-click in the Class Library and select New > Toolbar; then rename the toolbar in the Class Library.
You can add new objects to the new toolbar by dragging objects from the Class Library directly to the toolbar in the Toolbox and dropping them there.
In the context menu of the objects in the toolbar you can open the objects, show their class or delete them from the toolbar.
