In order to specify tensions for individual cables:

  1. Place your conductor span(s)
  2. Using the move and select tool, click on a conductor span and scroll down to the 'Catenary Definition' section within the properties tab (if the properties tab is not available, press the '+' next to any open tab and add it)
  3. Click on the drop down menu and select the 'Separate Constraints Per Cable option'
  4. From here, you can then define the cable tensions for each cable as required and the model UI will update to portray the different tensions in your design
