Depending on the choice of property page you can see a Geographic View or a List View of the Line structures.
There are two different methods for specification of the line structure.
In the List View you can create a new line structure clicking on the "New line" button. By selecting a Line structure in the Line list and clicking on the "Delete line" button you can remove this line structure. For each line structure you can specify the name of the line structure and whether the line structure should be active or not. The specification of detailed information for each line structure is made subsequently. From the List View page you can navigate to the dialog for specification by clicking on the "Go to ..".
In the Geographic View it is also possible to create a new line structure by selecting "Add New line" from the context menu. Click once to add a point and twice to add the end point of the line structure. You may edit the individual line structure by selecting and moving the specified points (point, click and drag) or using the functionalities from the context menu (point, right-click). The additional information for the line structure is entered subsequently.
