In the case of what you said, I would have expected the following legs to be default (right): 1-2 2-3 the following legs to be vertical: 3-4 4-5 5-6 6-7 7-8 then the following legs to be right: 8-9 Instead, leg 2-3 will be vertical, and leg 7-8 will be right. At least in my head, "extend vertical 3" feels like it should mean "everything from station 3 onwards". I think Bruce also expected this, given what he wrote in the wiki "extend" article: https://therion.speleo.sk/wiki/extend "Usually this option will not work as described, unless it is preceded by one or two extend right <leg> statements." So perhaps this is either a generic misunderstanding; Therion assumes that by <station> it means <the leg that goes *to* the station>. We assume that by <station> it should be <the legs that come *after* this station>. I don't know which of those is right. I have also never used this with Survex, so I don't know if Survex agrees with Therion - Perhaps Wookey can say? _______________________________________________ Therion mailing list [email protected] https://mailman.speleo.sk/listinfo/therion
