Been trying to draw up a survey using tunnel. I have linked the walls to the centreline and still the order of the overlying passages is in the wrong order. How can this be corrected?

Ive been trying to figure out how to remove the centreline from the finish sketch, with no sucess. Anyone know how its done?

Is it possible to use the sketch from pocket topo as a background to draw over the top? In a similar fashion to Therion.

Trying to get my head round Therion, so far i have been shown some basics. I have printed the manual and cannot find the answers I'm looking for. I'm surveying using distox and pockettopo, i am also used to using Survex. Ive put the notes into the text editor, I've also got the map imported as...

Can't get my head round using splay in survex. Whats the format for omitting a splay shot?

anyone got a spare kicking about for cheap/free? cheers

Has anyone got a surplus duo battery box? Needed for a self design light.

Im going to use 20 x 10Ah 1.2V D cell batteries in series. Will a battery charger designed for SLA batteries be ok? I have found this one, just wanted to make sure its right before i start spending. http://www.rapidonline.com/Electrical-Power/Batteries/Chargers/24V-1A-SLA-Battery-charger/72474...
