Next, open up the property dialog of the T-Line part by double-clicking on its symbol in the [[Schematic Editor]]. You will see a list of the device's [[parameters]]. You will keep the default characteristic impedance value of Z0 = 50Ω, the default effective permittivity value of eeff = 1.0, and the default zero attenuation constant. Change the length of the line segment to 75mm. To do so, select the "len" row in the parameter list, and type in the value 75 to replace the default 10, and click the "Accept Value" button of the dialog.
{{Note | You can rotate a selected part clockwise using the keyboard shortcut Ctrl+R or rotate it counter-clockwise using Ctrl+Alt+R. You can also flip a selected part horizontally using the keyboard shortcut Ctrl+F or flip it vertically using Ctrl+Alt+F.}}
