I have an idea that might just be crazy enough to work. If only I could get Therion to output an XVI file containing the stations and splays I am interested in. Imagine there are three parallel passages, running over the top of each other. I know I want a cross section of all three passages at once; at station 12 in the top passage, station 78 in the middle passage, and station 5 in the bottom passage. source "cystanog.th" select [email protected] select [email protected] select [email protected] export map -projection [elevation 355] -fmt xvi -output "test.xvi" If only this worked (it doesn't - you can only select a map or survey, not a single station), I would have the positions of all three passages relative to each other. I could then use those positions to place the cross section scraps for each passage, and include that as a scrap in the overall cave map. So ... can I get Therion to output just those 3 stations - and optionally their splays, projected on a bearing? (I am thinking that yes, I could make a subsurvey for each of these stations, equated to the parent survey's station with the same number. Then use "select" with the subsurvey's name. But this is so very messy, and I was hoping for a cleaner solution, that didn't require modification of my source data.) _______________________________________________ Therion mailing list [email protected] https://mailman.speleo.sk/listinfo/therion
