Thanks Rhys for pointing this out and discovering, that it is a splay shot issue. I have recently seen this behaviour also in my dataset but had no time yet to investigate. With knowing that it is a splay shot issue I hope it will be much easier. Best regards, S. On Tue, 19 Jan 2021 at 15:10, Rhys Tyers <rhystyers1@gmail.com> wrote:
Hello,
I have noticed something that I am not sure if it's a bug or not. I am trying to export a selected bit of a survey as a loch file:
source "data/system_migovec.th" select vrtnarija_vilinska@system_migovec export model -o outputs/vrtnarija.lox
This seems to correctly export the centerline only for "vrtnarija_vilinska" but if I turn on the walls in loch then other bits of the survey are shown.
Centerline correct: [image: image.png] With walls there are other bits of passage shown: [image: image.png]
These seem to correspond to bits of passage that have splays and LRUD data so it seems like those aren't correctly filtered out using the "select".
Using: therion 5.5.6 (2020-12-27) - using Proj 6.3.1, compiled against 6.3.1
Thanks, Rhys
