<div class="moz-cite-prefix">Hi Vladimir,<br>
<br>
Finally I have choose the easy way (see the attached figure).
Yours comments and other forum members convinced me. And it's more
easy also to coordinate with new Topodroid symbols. <br>
<br>
Now I have two new user anchor symbols: u:anchor_artificial and
u:anchor_natural which I combine with rope section with or without
rebelays and anchors. <br>
<br>
I put the mpost code if others users want use it. <br>
I have choose a brown colour to rigging (rope and anchors). <span id="result_box" class="" lang="en"><span class="">As you can not
choose the color of the user symbols, with "symbol-colour", I
had to define it in the mpost.</span></span><br>
<br>
Thanks,<br>
<br>
Evaristo. <br>

<div class="gmail_default" style="font-size:small">Indeed the
line rope needs some additions in an elegant way :).
Occasionally I have also wanted to make a Y-anchor without the
dot in the middle. But I hadn't had the time to add this
feature. It can be done by adding extra line point options.
Similar to "adjust horizontal", "l-size", etc for "line:wall".<br>
</div>
<div class="gmail_default" style="font-size:small">This will
require modifications to both the Metapost code to draw the
symbol, and to the therion c++ code that parses the options.<br>
</div>
<div class="gmail_default" style="font-size:small">It would be
possible to draw different types of anchors depending on the
line point option, but I am not sure if it will be easy to
reflect the used anchors in the legend.<br>
<br>
</div>
<div class="gmail_default" style="font-size:small">Actually it
would be best if there are both ways of setting an anchor:
with a line point option, or with a separate point "anchor"
with different options. The "anchor" point already exists, but
is only one type.<br>
<br>
</div>
<div class="gmail_default" style="font-size:small">When I draw a
rope I always use it with "rebelays off" now and draw the
rebelays with a Bezier line. This allows me better control,
because the automatic rebelay curves don't always fit well in
the pit shape.<br>
<br>
</div>
<div class="gmail_default" style="font-size:small">Evaristo, if
you want to work on the code, I can try to help. The above are
all nice ideas, like many others, but I personally don't have
the time to experiment with implementing them.<br>

<p>Hi,</p>
<p>I greatly appreciate the improvement made by Vladimir
at the rope line symbol.</p>
<p><a class="m_8479800413231117111moz-txt-link-freetext" href="https://www.mail-archive.com/therion@speleo.sk/msg05992.html" target="_blank" moz-do-not-send="true">https://www.mail-archive.com/<wbr>therion@speleo.sk/msg05992.<wbr>html</a></p>
<p>With this symbol you can control if the rope section
has anchors and rebelays, as line options. This options
are global to the line: have or not rebelays or
anchors. <br>
</p>
<p>Now a I need to go more ahead, I want control the
anchor type (natural: tree, block, etc or artificial:
spit, multimonti, parabolt, etc) in every point and the
rebelay in previous section. I want a <span id="m_8479800413231117111result_box" class="m_8479800413231117111short_text" lang="en"><span>round
point for artificial anchor (like the Vladimir
symbol) and a triangle point for natural anchor.<br>
</span></span></p>
<p>When we rig with Y knots and deviators you need to
control the line section without rebelays and anchors, <span id="m_8479800413231117111result_box" lang="en"><span>so
that the rope is straight and the knots do not
appear as anchors. (see attached figure). <br>
</span></span></p>
<p><span id="m_8479800413231117111result_box" lang="en"><span>Now
I have to way to implement this in Therion: the easy
and the elegant.</span></span></p>
<p><span id="m_8479800413231117111result_box" lang="en"><span>Easy.
Create two new point symbols for natural and
artificial anchors. And use the rope line symbol
with rebelay and anchor OFF in the rope section with
Y and deviators, and ON in the other sections. <br>
</span></span></p>
<p><span id="m_8479800413231117111result_box" lang="en"><span>Elegant.
Create a new rope line symbol, where I can control
in every point the anchor type (Natural, Artificial
or None, for knot) and the rebelay rope effect in
the previous rope section. I think we can do this by
defining options to the line point. I know other
have implemented similar option, like "adjust
horizontal". To do this a need code examples with
similar option implementation to inspire me. <br>
