I export to xvi, and open the exported .th2 sketch by Topodroid.
<span id="result_box" class="short_text" lang="en"><span class="">You

The result is better, but splay are not a the same position in the

<p class="MsoNormal"><span style="mso-fareast-language:EN-US">I
think the extend options provide control of the non-splay

right, vertical, not at all, or not visible.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">The
splay legs should just ‘wobble around’ as a second order
effect, in response to the extend parameters applied to the
non-splay legs.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">So
the only sensible behaviour for splays is ‘extend auto’, and
my observation is that this is already coded into PocketTopo
and Therion, and so there is no reason to require the user
to invoke ‘extend auto’ manually.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">As
noted in previous threads, Therion and PocketTopo do manage
to orient splay legs differently. Quite often I have to
mentally reorient splays when drawing in Therion Drawing
Editor. Neither application seems to do it perfectly, but
then because the shape of the extended centreline network is
as much an arbitrary artistic choice on the part of the
user, as it is based on hard numeric data, there is perhaps
no ‘right approach’ for the software to take. I suspect that
I have observed that TopParser can affect the orientation of
splays as well, but I am not sure of that.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">I
think the right approach is to aim for Therion (and
PocketTopo, TopoDroid) to orient splays automatically, based
on the extend directions of the incoming and outgoing
non-splay legs. If the applications were to allow direct
user control of splay extend direction, then the statements
should not be able to be confused with existing statements
that control the non-splay legs (ie adopt extend splay left,
extend splay right, extend splay vertical, extend splay
auto). Perhaps this topic is something the authors should
collaborate on to achieve a consistent behaviour?<o:p></o:p></span></p>

I have commented all the splays "extend ignore", and
Therion is doing <br>
now a good job, ignoring the appropriate leg (extend
ignore 83 92). All <br>
the splays "extend ignore" was confusing the Therion
compiler.<br>

This data is an export from Topodroid, that incorporates
the "extend <br>
