3D files generated by Therion do not allow you to click on splay legs in Aven

Description
Use Therion to export a .3d file that has anonymous splay legs ("-"). Open the .3d file in Aven. Enable splays (eg. "view - splays - fade"). Try to click on the end of a splay leg; nothing happens, they are not selectable. This makes it impossible to measure distances between splays, such as when trying to measure the height of a pitch from its lip to the base.
Use Cavern to export a .3d using equivalent data with anonymous splay legs (".."). This time you can click on the end of a splay leg.
It is possible that this is because Therion has intentionally chosen a different type of point for the end of the splay. If so, this is a Therion bug rather than a Survex bug.
Tested on Windows 10 and Linux.

I have attached minimal test files. The data is basically this:
1 .. 1 0 0
1 . 1 90 0
Therion gets this:
LINE 1.00 0.00 0.00 [cave] SPLAY
While Survex gets this:
LINE 1.00 0.00 0.00 [cave] STYLE=NORMAL SPLAY
The Survex version also gets these two, which are not present in the Therion output:
NODE 1.00 0.00 0.00 [] UNDERGROUND ANON
NODE 0.00 1.00 0.00 [] UNDERGROUND ANON WALL

Seems therion doesn't set the survey style, but that's no big deal. That information is there to allow features like "Colour by survey style" so you can see what's "normal", what's "diving", what's "nosurvey", etc, but current aven doesn't actually have any such features. It didn't used to be in .3d files before version 8 (introduced by Survex 1.2.7 on 2013-07-27) - therion's 3d export code probably pre-dates this.
The missing NODEs for the stations at the end of splay legs explain why you can't find the ends of splay legs with the mouse, so really this is a therion bug with how it exports splays in .3d format.

This isn't a bug in Survex, so closing. Please report to the therion developers.
I've opened #113 about colouring by survey style so that doesn't get forgotten.

Thanks for the analysis. Moved over to https://github.com/therion/therion/issues/157
If you look at minimal examples with
dump3dhow do they look different?
