Sobre el Sailcut CAD</h3></div></div></div><p>Sailcut es un software para el diseño de velas desarrollado
para paños planos. El Sailcut se puede usar tanto para velas de
cuatro lados tipo cangreja como para mayores y foques Marconi de
tres lados.</p><p>La primera versión del Sailcut fue desarrollada en 1978 y
usada por Robert Lainé para fabricar las velas de su barco
"Flying Sheep III", un ¼ Ton IOR. Sailcut ha estado
disponible en la web desde 1994 y es utilizado por muchos
fabricantes de velas, tanto amateurs como profesionales, para
cruceros, regatas y recientemente para barcos de
radiocontrol.</p><p>Sailcut se basa en una única definición matemática para la
superfície vélica que asegura un perfil aerodinámico y
uniforme.</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="idp48610400"></a>1.2. ¿Cómo obtener el Sailcut CAD?</h3></div></div></div><p>Se puede descargar la última versión del Sailcut CAD desde
la página principal en
<a class="ulink" href="http://www.sailcut.com/" target="_top">http://www.sailcut.com/</a>. También está
disponible en binario (compilado) y en código fuente.</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="idp48612288"></a>1.3. Información técnica sobre el programa</h3></div></div></div><p>Sailcut CAD se ha escrito con la intención que sea
transportable. El programa fuente es el C++ utilizando la
librería Qt de Trolltech para los gráficos y el OpenGL para la
visualización en 3D de las velas. Sailcut CAD se puede compilar y
funcionar bajo GNU/Linux, Microsoft Windows y MacOSX.</p></div></div><div class="sect1"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="s.using"></a>2. Usando el Sailcut CAD</h2></div></div></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="idp48614944"></a>2.1. Últimas notas</h3></div></div></div><p>Al igual que la versión 0.6.5, el Sailcut CAD usa
diferentes extensiones para cada tipo de archivo instalado en
lugar de los finales con extensión ".xml". Si deseamos
abrir nuestras velas creadas con la versión anterior del Sailcut
CAD debemos renombrar el archivo de definición de vela así como
las extensiones con ".saildef". Al abrir el archivo
resultante, todos los archivos se conservarán excepto los datos
para el molde.</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="idp48616944"></a>2.2. Preferencias de usuario</h3></div></div></div><div class="sect3"><div class="titlepage"><div><div><h4 class="title"><a id="idp48617584"></a>2.2.1. Preferencias de archivo</h4></div></div></div><p>Las preferencias se almacenan en un archivo llamado
<code class="filename">.sailcutrc</code>. Bajo UNIX este archivo se localiza en
el directorio raíz y en Windows está en <code class="filename">Documents and Settings\USUARIO</code>.</p></div><div class="sect3"><div class="titlepage"><div><div><h4 class="title"><a id="idp48619680"></a>2.2.2. Internacionalización</h4></div></div></div><p>Como en la versión 0.5.5, el Sailcut CAD tiene soporte
para la internacionalización. Al arrancar el programa, podemos
seleccionar el idioma que nos interese en el menu
Ver->Idioma.</p></div></div></div><div class="sect1"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a id="s.creating"></a>3. Crear una vela</h2></div></div></div><p>Cuando iniciamos Sailcut CAD, se presenta una vela por
defecto y en la parte superior de la ventana encontraremos menús
desplegables. El menú ARCHIVO se usa para cargar una vela
existente, GUARDAR los parámetros de la vela y EXPORTAR los paneles
desarrollados.</p><p>Se puede modificar las dimensiones de la vela utilizando el
menú Ver->Dimensiones.</p><p>Con el menú Ver->Molde podremos modificar el perfil de la
vela.</p><p>Y en el menú Ver->Aparejo visualizaremos varias velas con
diferentes aparejos.</p><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="idp48624848"></a>3.1. Pantalla Dimensiones (menú Ver->Dimensiones)</h3></div></div></div><p>El programa permite diseñar tanto una vela triangular como
cuadrangular. La clásica vela Marconi se diseña esencialmente
igual que una Cangreja pero con un pequeño puño de driza.</p><p>La superficie de la vela se genera desde unas sencillas
ecuaciones que definen el perfil en todas las alturas. Dichos
perfiles se basan en los extremos de las velas que han sido
definidos por la longitud y alunamiento en cada lado y por el
twist de la vela. En la ventana "Dimensión" hallaremos
los parámetros que definen la vela.</p><p>Al pulsar el botón "Calcular" el programa evalúa
y visualiza los datos auxiliares. Estos datos aparecen en
pestañas de color y que pueden modificarse. Si el color es rojo,
significa que el valor excede del límite superior; si es amarillo
indica que está por debajo del límite aceptable y debe
cambiarse.</p><p>Una vez finalizada la entrada de datos de dimensiones,
pulsamos OK para visualizar la vela en formato 3D.</p><div class="sect3"><div class="titlepage"><div><div><h4 class="title"><a id="idp48628896"></a>3.1.1. Pestaña "Geometría del Aparejo"</h4></div></div></div><p>El primer paso es seleccionar el tipo de vela con la que
vamos a trabajar y entrar los datos que definen la geometría
del aparejo y el plano vélico (ver la Figura 1.)</p><p>Seleccionar el tipo de vela marcando bulón deseado:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>FOQUE para cualquier vela de proa,</p></li><li class="listitem"><p>MAYOR para cualquier vela envergada en el

proper relative position with the "rig viewer".</p><p>

</p></div><div class="sect3"><div class="titlepage"><div><div><h4 class="title"><a id="idp48636368"></a>3.1.2. Pestaña "Dimensiones de la vela"</h4></div></div></div><p>Aquí es donde se introducen las dimensiones de la
vela.</p><p>En una vela mayor, el valor mínimo para la longitud de la
percha (galleta del puño de driza) es de 5mm. Cualquier valor
inferior dará siempre por defecto 5mm. El ángulo de percha
viene definido como el ángulo entre el mástil y la baluma que
puede ser hasta 90 grados.</p><p>El alunamiento del pujamen, la baluma y la percha
extiende la vela más allá de su línea recta.</p><p>El alunamiento negativo equivaldrá a un hueco en la parte
exterior de la vela.</p><p>La posición del alunamiento se expresa en porcentaje en
el correspondiente lado de la vela calculado desde la parte más
baja o más externa del lado.</p><p>

</p><p>Dimensions and angles defining the sail plan are
expressed in millimetre and degrees.</p><p>Length of the sail sides and diagonal are the 3D straight
line distance between the corners of the sail.</p><p>The actual length on the finished sail lais on the floor
can be slightly longer depending on the shape of the sail. For
example, the foot length entered in the screen below is 3600
mm. If the foot camber is null then that will be the actual
distance between clew and tack (straight foot) of the finished
sail. If a 10% camber is entered for the foot depth, then the
actual foot will be the length of the arc which has 10% camber,
that is 2.7% longer than the straight line foot length.</p><p>Having entered the sail main dimensions you can press on
the "Compute" button to obtain additional
informations on the sail, like the X-Y coordinates of the
corners of the sail, the perpendicular length LP measured from
the clew to the luff as well as IRC racing rules width.</p><p>The X-Y coordinates of the sail corners are usefull to
quickly adjust the data entered. For example if you find that
the clew height (Y) is way below or above the height of the
tack when you would like it to be leveled, then you can
substract or add the difference to the leech length.</p></div><div class="sect3"><div class="titlepage"><div><div><h4 class="title"><a id="idp48646192"></a>3.1.3. "Layout" box</h4></div></div></div><p>Click on the radio button corresponding to the desired
layout of the sail. The layout of the panels does not affect
the shape of the sail which is defined by its dimensions and
its mould. Except for the Radial cut layout, the number of
panels is determined by the cloth width and seam width entered
in the "Cloth" box.</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>The most commonly used layout is the
"Crosscut". The panels are laid perpendicular to
the straight line joining the peak to the clew of the
sail.</p></li><li class="listitem"><p>The "Twist foot" layout is similar to the
cross cut except that the lower panels are rotated such
that they do not intersect the foot of the sail.</p></li><li class="listitem"><p>The "Horizontal cut" layout lay the seams
in the horizontal plane. This option can be used to
visualise the profile of the sail at various levels and to
output files with the 3D coordinates of the sails for use
by CFD tools.</p></li><li class="listitem"><p>The "Vertical cut" layout places the panels
parrallel to the straight line joining the peak to the clew
of the sail. This is the favorite layout for the old
timer's main sail.</p></li><li class="listitem"><p>The "Mitre cut" layout is the favorite for
the old timer's genoa. The sail is divided in two
parts by a line joining the clew to the mid point on the
luff and the panels organised to be perpendicular to the
foot in the lower part of the sail and perpendicular to the
leech in its upper part.</p></li><li class="listitem"><p>The "Radial cut" is used mostly for
competition as the cloth is mostly aligned with the
directions of maximum strain. When using the Radial cut
option it is important to understand the definition of the
number of sections, number of radial gores and number of
luff gores (see figure below).</p></li></ul></div><p>
</p><div class="figure"><a id="fig.head_gores_definition"></a><p class="title"><strong>Figura 3. Radial cut gores definition</strong></p><div class="figure-contents"><div class="mediaobject"><img src="head_gores_definition.png" alt="Radial cut gores definition" /></div></div></div><p><br class="figure-break" />
</p></div><div class="sect3"><div class="titlepage"><div><div><h4 class="title"><a id="idp48658304"></a>3.1.4. "Sail shape" box</h4></div></div></div><p>You enter there the depth of the sail at 3 levels, near
the foot, in the middle of the sail(the exact position being
defined in the mould screen) and near the top of the
sail.</p><p>The twist angle is the angle expressed in degrees by
which the top of the sail is rotated with respect to the foot.
The twist is globally determined by the amount by which the
apparent wind at the top of the mast is rotated with respect to
the apparent wind at deck level. For a jib the twist is
sometime driven by the need to have the upper part of the leech
sufficiently open to clear the spreaders. For a mainsail the
twist is also driven by the ability of the rig to carry the
tension in the leech, in particular a gaff rig will have more
twist in its main sail than a Bermuda rig. It is important that
the twist angle entered in Sailcut reflects the reality of the
shape of the leech when sailing in an average wind.</p><p>The sheeting angle value is the actual sheeting angle
measured from the boat centerline when the sail is set on the
boat. For a jib the minimum value is 5 degrees. The value is of
importance to ensure that the sail is properly positioned when
displayed in the "rig viewer". You can then visualise
for example the slot between a jib and the main sail as set
when sailing.</p></div><div class="sect3"><div class="titlepage"><div><div><h4 class="title"><a id="idp48661712"></a>3.1.5. "Cloth" box</h4></div></div></div><p>Enter there the width of cloth used, the width of the
seams between adjacent panels, the width of material to be
added to the leech to make the leech hem and the width of
material for the foot hem and the other edges hems.</p><p>The figure below describes de location of the various
hems and seam width.</p><p>Sailcut will compute the panels such that they fit within
the declared cloth width including the seam and hems width as
appropriate.</p><p>Note that when using the radial layout, the seam width
between horizontal sections will be twice the width of the seams
between adjacent panels of the same section.</p><p>

located at the bottom (foot) the middle (maximum depth level) and
near the top.</p><p>The vertical position of the maximum depth profile is
controlled by the vertical slide bar to the right of the left
vertical frame.</p><p>The luff shape and the leech shape can be adjusted for the
Top profile and Middle profile only. The foot profile is always
an arc of circle.</p><p>In order to avoid that the leech makes a hook in the upper
part of the sail when the wind increases it is recommended that
the Top profile luff shape value be higher than that of the
middle profile and that the leech shape value at the top be lower
than the middle value.</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="idp48669920"></a>3.3. Rig viewer (View->Rig menu)</h3></div></div></div><p>This viewer is used to display several sails on the same

already created and saved with Sailcut.</p><p>Once a sail is added to the rig viewer the sail information
frame appears below and it is possible to translate the sail in
the 3 directions by adding X-Y-Z displacement values. If you have
misplaced a sail use the Reload button to recover the initial
sail. You can also use the Remove button to eliminate a sail. 2
slides allows you to ratate the rig in azimuth and elevation and
view the ig from any vantage point.</p><p>The File->Save menu entry is used to save a rig with a
combination of sails.</p><p>Rigs which have been saved can be later opened as an entity
with File->Open menu entry.</p><p>Note that the rig viewer window must be closed to allow you
to return to the main screen of Sailcut.</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a id="idp48674544"></a>3.4. View controls</h3></div></div></div><p>It is possible to zoom, pan and rotate the sail in the view

panel (edge of cloth). The dX,dY coordinates are relative to
the straight line joining the end of the corresponding edge
and it should be remembered that the origin of dX is at the
left end of the edge and positive value of dY indicate that
the point is left of the straight line joining the origin to
the end points of the edge.</p></li></ul></div><p>The printout scaling is such that the sail drawing and the
largest developed panel automatically fit in one page. For
printing panels to a precise scale it is preferable to export the
developed sail in a DXF file and use a CAD package to print the
panels.</p><p>
