[Therion] Extended elevation direction opposite to sketch (TopParser and PocketTopo export to Therion)

[Bruce Mutton]

Has anyone come across this issue with changes in direction of extended
elevations, when PocketTopo files are processed with TopParser or exported
to Therion?





ie, the centreline developing in the opposite direction to the original
sketch?

 

The extended elevation is OK in PocketTopo, but regardless of the method
used to parse it to Therion, the second part of the survey extends the wrong
way in the xvi file. 

In this file, station 1.0 is where the survey started, first downstream,
then we went back to station 1.0 and continued upstream.  The second part of
the survey has the legs 'flipped' so that they extend left.

 

I eventually worked around this by deleting the downstream legs.  Now the
second set of legs starting from station 1.0 correctly extend left.

I'm wondering if this behaviour is due to having two 'branches' of survey
legs extending from the first station in the survey, 1.0, with one extending
right, and the other left?

Perhaps this is a limitation or bug with the code that parses from .top to
.xvi (for both TopParser and 'Therion method')?
