There's also "File->Export As..." in aven, but neither supports passage
dimension data yet:

The old postscript printing code is now the "EPS" option in aven's
export code.

If you're prepared to massage data formats yourself, you can use dump3d
to produce parsable text output from a .3d file.  You'll need to build
it though - if you build Survex from source, you can then "cd src" and
"make dump3d".
