I see it too now. I have not realised you could include just a centreline in the map. It shows every survey station and leg in the cave, rather than just those included in scraps right? When I add that my altitude baseline is set to 0m like yours using 5.3.16
I've not done this before as I had assumed I could only see survey sections which were drawn in scraps. I can see how it is useful to be able to render centrelines and stations for the entire system regardless.
