Yeah, I'd call it a bug now. I think I first noticed this behaviour early in 2015, and if that was the case it would have been around version 5.3.16 (the date and version on my first decent extended elevation map).
It would have been my first forays into extended elevations and I quickly switched from in-line to data blocks for extends for the reasons outlined here <https://therion.speleo.sk/wiki/extend> . Because I was already drawing completely electronic, not using pdfs or pencil sketches, I was using the xvi s exported from PocketTopo and so the Therion exports were a curiosity only. Placing the extend statements in a block was essentially an undocumented feature, and so I assumed it was my fault for stretching boundaries. And I assumed that if I placed the extends in-line, the splays would behave. I am not sure though, as I have not carried out any explicit tests. I’ve really only been prompted to bring it up now because a) we’re making good progress on extend behaviour and blocks of extend statements are becoming mainstream, and b) I have inherited some survey notes for which the sketches will be best drawn in pencil over a pdf printout.

Wait ... that's a bug?! I thought Therion just didn't handle splays well compared with Survex. > Notice how all the splays are extended in the direction that the legs > are extended in. Drives me crazy. Pretty bad behaviour, and makes all the splays useless for drawing extended elevations. Does this mean that there is actually a solution to this, by using inline extend commands? _______________________________________________ Therion mailing list <mailto:[email protected]> [email protected] <https://mailman.speleo.sk/listinfo/therion> https://mailman.speleo.sk/listinfo/therion
