To invoke the editor, right-click over the Transmission Line Configuration component (without selecting it) and select Edit Definition… (or double-click) as shown below:
The editor will open within the main window. As shown below, the default view is the Editor section, where the transmission line is graphically defined.
By default, the editor section will contain three graphical objects:
Definition Canvas (<Definition Name>): Located in the top-left corner, this object simply displays what has been entered into the corresponding Transmission Line Configuration dialog. This object is for display only and cannot be modified from inside the editor.
Frequency Dependent (Phase) Model Options: This component represents the transmission line model being used, and by default is the Frequency Dependent (Phase) model component. The parameters of this component may be edited by either a left double-click on the component (or right-click and select Edit Parameters...) to bring up the corresponding dialog window.
Entry of Ground Data: This component (called the Ground Plane), usually located near the bottom of the editor window, represents the transmission line ground return path. The parameters of this component may be edited by either a left double-click on the component (or right-click and select Edit Parameters...) to bring up the corresponding dialog window.
A fourth object required is the definition of the transmission line itself. This definition can be a geometrical cross-section of the Transmission Line Tower component, or can be a Manual Entry of Admittance/Impedance Data (Bergeron model only). In either case, this is left for the user to add manually.

Transmission Line Tower Components |
Tower components can be added to the editor in a couple different ways. The easiest and most straightforward way is to use the ribbon control bar. Simply select one of the available towers and place it on the Schematic canvas. See Adding Components to a Project for more details.
Another way is to use the context menu. On the Schematic tab, move the mouse pointer over a blank area of the window. Right-click and select Add Tower Cross-Section. A sub-menu will appear containing a list of all loaded library projects. Each of these will contain a list of all transmission line tower components available in that particular library. Select a tower and it will be automatically added.
You can also copy and paste tower components directly from from the master library. Open the library in Schematic view. Select a tower component, then right-click on the component and select Copy (or press Ctrl + c). Open the Editor tab, right-click over a blank area and select Paste (or press Ctrl + v).
When finished, you should have something similar to that shown below:
NOTE: The graphical location of the tower component does not affect the results. However, the tower (or towers) should be positioned to allow for ease in readability. That is, directly on top of the Ground Plane component.
Multiple towers may be added to a single configuration. Just remember to ensure that the conductors are numbered properly within each of the tower components, and that the x-positions of the new towers in the corridor are adjusted. Also, any conductors added by the additional towers must be reflected in the corresponding Transmission Line Interface components (if in Remote Ends mode).
Tower parameters can be edited through the corresponding tower parameters dialog window. Right-click over the tower component (without selecting it) and select Edit Parameters... to access this dialog.
