The plan-based code obviously works well for plan-based surveys. However, if the site is a shaft, placing stations on a plan for (near) vertical legs is problematic?

0) Follow Patrick Warren's Workflow advice. (ReadMe.md in https://github.com/patrickbwarren/inkscape-survex-export/releases/tag/v2.0)
1) (stations planned layer) Mark intended stations down the shaft so that (in the case of 0189) it is possible to add extra stations horizontally out to the ends of the rift. (These stations are not shown)
2) All the bearings will be 110 or 290 with L,R,U,D added later to take account of the narrowness all the way down (big assumption!)
3) Scale and Nm lines easy to do.
4) Have two screens so that the plan is as large as possible while still viewing the elevation on the second screen.
5) SVX EXTENSION: On the plan, I only marked some of these stations. (Shown as red circles, Inkscape start-end-middle markers)
0 1 6 9 11
then 11 12 13 then 9 14 15 16 17
6) Scale bar: line should be exactly two points. This error made me change the line widths to 2 points before I realised what was meant!
7} Rename the generated station numbers to agree with original 'stations planned' and alter *equates and *export
8) *data cylpolar from to tape compass depthchange
9) Put in depth changes for these few stations, just as a check.
10) Add *FIX path5632.0 0 0 0 as a temp measure. Without this, altitude range goes from 28 down to -10??
11) Alterations 7 - 10 saved as 0189-R-02.svx
12) Manually insert other stations into svx file and alter depthchanges. Assuming that stns 2,3,4,5 are vertically below 1. (Should have had another station here to take account of the deviation). Similarly, stns 7,8,10.
13) Insert the shots (*FLAGS SPLAY) out into the rift 1 - 1a, 1 - 1b etc. Each of these is horizontal along the line of the rift about 112 - 292.
14) Add LRUD for most of the stations. This is 0189-R-03.svx
It took longer to produce the file that it would have done to survey it (and have a drink afterwards). That's the nature of the cave.
Simon has produced 0001.3d in a very different manner, also a vertical site. Both methods are "long-winded". Is there a third way?
