[Therion] how to input shots from the station to the cave wall?

Hi, what is the best way to enter measurement data from the current station to the cave wall? Basically this is thought to replace LRUD with real measurements. The form how the data is generated looks like: 1.0 1.1 12.32 234.5 -12.2 # from to tape compass clino 1.0 2.33 123.3 0.1 # from tape compass clino 1.0 3.44 345.5 76.5 # from tape compass clino ... The measurements in line 2 and 3 should not count for cave length too. Is there a way to use this measurements in generation of the 3d volume model? Any help is welcome. Wolfgang
