#121 fixed brew upgrade issues on macOS Olly Betts Simon Murphy
Description

Hi, I've recently migrated to BigSur? (the latest macOS), which meant survex no longer loaded.

I've just done a brew upgrade survex to get the latest version (I'm now at 1.2.43), hoping this would resolve the problems.

When I run

aven

I get (for user sjm):

dyld: Library not loaded: /Users/sjm/Developer/opt/proj/lib/libproj.19.dylib
  Referenced from: /Users/sjm/Developer/bin/aven
  Reason: image not found
[1]    67839 abort      aven

I did a bit of googling and tried to

brew unlink survex

then

brew link survex

again, but no luck.

When that didn't change anything, I tried

brew reinstall survex

but still no luck.

I tried

ln -s /Users/sjm/Developer/Cellar/proj/7.2.1.reinstall/lib/libproj.19.dylib /Users/sjm/Developer/opt/proj/lib/libproj.19.dylib

but still no success.

Thanks in advance for your help. Simon.

#112 invalid 3D files generated by Therion do not allow you to click on splay legs in Aven Olly Betts Tarquin Wilton-Jones
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.
