Exporting to Survex for passage tubes viewing

[Luc Le Blanc]

Hi,

An Auriga user tells me the SVX files exported by Auriga do not allow
viewing passages tubes in Aven. Another caver fiddled with his data
and returned a tube-capable SVX file. When I compare both SVX files, I
see each shot line (data normal) is now followed by more than one
passage dimensions (data passage) line, providing the passage
dimensions at a station that is not part of the current survey shot,
but that is connected to the dimension-bearing station of the current
shot.

Another way to produce a tube-capable SVX seems to be an export where
all passage dimensions are bundled at the end of the file, after
survey shots and splay measures.

Questions:

* is placing passage dimensions after each survey shot in the SVX file
a requirement, or is the quoted behavior a mistake?

* are splay measures used to build the tubular view? (it seems they aren't)

* when activating the tubular view, I get very long ghost lines that
do not correspond to any survey shot - could this be a loop-related
bug?

Regards,
