One of the reasons for having been so loyal to the program is its powerful visualizers (Cave Viewer and CaveXO); and at a time when the data was entered by hand its powerful data editor (Cave Editor).
In Compass there are 2 basic types of concepts: "Surveys" assimilable to the Therion "Centerlines" and "Section", used normally to define Caves or caves parts like Therion "Surveys".
With the "Complex Plotting Options" menu of the "Cave Viewer", I can show, hide, color, symbol, etc, of the centerlines and walls by section, surveys, dates and distances. It's a very powerful tool to analyses complex caves systems.
