The context menu in the main window contains the following commands:

Via Add class... and Add subclass... you can build your class system.

	Note
	Only useful commands will be displayed. Upon starting the building of the tree structure for example, only Add class... is shown.

Parent class: Shows, if available, the name of the superordinated class. Type: In the list field select the desired class type. Internal id: Is automatically entered. ID: Is automatically entered. Name (<chosen standard language>): Enter the desired name. This term will be displayed in the class tree. Finally confirm with OK.

Dialog box: Add class / Edit class

	Note
	The commands Add class... and Add subclass... will call up the same window. The dialog boxes in Edit class are also identical.

Example:

In the empty field -> context menu -> Add class...: ID "01" (already inserted), under "Name (german)" enter: "Bolts"

Context menu of "Bolts": Add subclass...: ID "01" (already inserted), under "Name (german)" enter: "Head cap bolts"

Context menu of "Bolts": Add subclass...: ID "02" (already inserted), under "Name (german)" enter: "Hexagon bolts"

Context menu of "Nuts": Add class...: ID "02" (already inserted), under "Name (german)" enter: "Nuts"

Context menu of "Nuts": Add subclass...: ID "01" (already inserted), under "Name (german)" enter: "Cap nuts"

Context menu of "Nuts": Add subclass...: ID "02" (already inserted), under "Name (german)" enter: "Hexagon nuts"
