InRoads Roadway Visibility equivalent in Power Geopak?

I've often used InRoads Roadway Visibility/Sight Distance tool when using corridor modeler, but we're trying to transition to Power GEOPAK SS4.  Is there an equivalent tool hidden somewhere that I could use the same functionality to verify sight distance through meshes or triangulated surfaces?  I'm currently using Power GEOPAK, 08.11.09.789.
