Therion itself is a command line application which processes input files written in text format and outputs 2D pdf maps or 3D models (.3d, .lox etc.). These can be created in any arbitrary text editor and contain the commands such as:

point 1303 1004 pillar

where point is a keyword for point symbol followed by its coordinates and a symbol type specification (see the features in the Therion book).

The Therion application has three different windows: an inbuilt text editor, the Xtherion Graphics User Interface, and a compiler window.

• cave.th contains the basic data of where survey stations are relative to one another, this is the equivalent of the .svx file in survex with some minor differences.
• cave-p.th2 contains the information about where the cave walls are, which areas are water etc... almost everything you see on the final pdf output.
• cave.thconfig* contains the compiling commands and controls which types of output we generate from the data. All are written in the therion language (for explanations on Therion syntax, you are again referred to the Therion book).
