From this corner, you can choose the transparency of the scene which will occur on each occurrence which are "sensible to X-ray". In order to fully benefit from transparency, you need to change the "Visual Behaviour" of your occurrence(s) in order to focus/highlight on the occurrences that matters  .

NOTE        A slider is available in the Panel "visualization" which allows you to choose exactly the % of transparency wanted.
