<br class="">
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 class="">
<br class="">
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 class="">
<br class="">
I put the mpost code if others users want use it. <br
class="">
I have choose a brown colour to rigging (rope and
anchors). <span id="result_box" class="" lang="en">As
you can not choose the color of the user symbols,
with "symbol-colour", I had to define it in the
mpost.</span><br class="">

Thanks,<br class="">

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 class="">

<div class="gmail_default" style="font-size:small">This
will require modifications to both the Metapost

code that parses the options.<br class="">

would be possible to draw different types of

am not sure if it will be easy to reflect the used
anchors in the legend.<br class="">
<br class="">
</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 class="">

<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

if you want to work on the code, I can try to

<p class="">Hi,</p>
<p class="">I greatly appreciate the
improvement made by Vladimir at the rope

<p class="">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 class="">
</p>
<p class="">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">round point for artificial
anchor (like the Vladimir symbol) and a
triangle point for natural anchor.<br
class="">
</span></p>
<p class="">When we rig with Y knots and
deviators you need to control the line
section without rebelays and anchors, <span
id="m_8479800413231117111result_box"
class="" lang="en">so that the rope is
straight and the knots do not appear as
anchors. (see attached figure). <br
class="">
</span></p>
<p class=""><span
id="m_8479800413231117111result_box"
class="" lang="en">Now I have to way to
implement this in Therion: the easy and
the elegant.</span></p>
<p class=""><span
id="m_8479800413231117111result_box"
class="" lang="en">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 class="">
</span></p>
<p class=""><span
id="m_8479800413231117111result_box"
class="" lang="en">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
