I find the description of "Opacity" in the 3D project menu opaque:

 "Opacity Can be used to reveal hidden spatial relationships, especially on overlapping objects of different colors and dimensions. The (surface) Opacity parameter permits the display of weighted combinations of nearest-point projection with either of the other two methods, often giving the observer the ability to view inner structures through translucent outer surfaces. To enable this feature, set Opacity to a value greater than zero and select either Mean Value or Brightest Point projection."

Can someone translate this into something taht explains how you would actually use it to reveal inner structures? I don't understand what the weighting is and how it would be combined with other projections.  Thanks- Dave
