 Note that the centreline generation is carried out as per normal, the stations and legs are just made ‘not visible’.\\ Note that the centreline generation is carried out as per normal, the stations and legs are just made ‘not visible’.\\
  
-**Important note:** with ''​left'',​ ''​right'',​ ''​normal'',​ ''​reverse''​''​vertical''​ and ''​hide'',​ Therion and Pocket Topo both apply the selected options to the leg before the station (in whichever direction Therion is traversing the centreline),​ as well as the ones following it - that is to say, it applies it to the leg that creates the station. Survex, on the other hand, applies the selected option to all legs after the selected station. This rare difference from Survex is by design. Because of this, and because it helps clarification too, it is a common approach to specify two lines, one saying to apply the option to the initial leg where it is wanted, and one saying to apply the option to that station. This also avoids some bugs mentioned above.+**Important note:** with ''​left'',​ ''​right'',​ ''​normal'',​ ''​reverse'' ​and ''​vertical'',​ Therion and Pocket Topo both apply the selected options to the leg before the station (in whichever direction Therion is traversing the centreline),​ as well as the ones following it - that is to say, it applies it to the leg that creates the station.
