Hi Xavier, Tarquin and Therion Mailing list, I've had a look through tarquins suggestions and tried a few, but am still struggling. (it will teach me to try and join walls in a chamber 20m wide, should have done 20mins more surveying the first time round, and joined somewhere more sensible!) I've got the project on http://cave-registry.org.uk/svn/Andara/Tresviso/Marniosa/therion/ I think it's openly available for people to pull off if you have SVN. The config file (thconfig.MMaster<http://cave-registry.org.uk/svn/Andara/Tresviso/Marniosa/therion/thconfig.MMaster>) has preselected the two problem surveys: source MarniosaMaster.th select District9.MarniosaMaster select alien_weaponry.MarniosaMaster or if you want a smaller selection of files, you could just pull District9 and Alienweaponry and create a .th with the following in it. #### survey problemcave input alien_weaponry/alien_weaponry.th input district9/District9.th join District9SP1@District9 alien_weaponry-1p@alien_weaponry map ProblemPlan -projection plan m1p@alien_weaponry District9Plan@District9 endmap centreline equate 12@alien_weaponry 12@District9 endcentreline endsurvey #### Regards, Alastair Gott.

All I want to do is join the black line where i'm putting the red line, but the yellow warping lines are thrusting it away again. If anyone has any thoughts it would be great to know them because there's something fundamentally wrong with what I'm doing! [cid:206d78da-11f6-41f7-b5bf-6b26829ce45f] Regards, Alastair Gott.
