+\maketitle

+\begin{abstract}
+\index{Paket@\textbf{Paket}!\texttt{pst-coil}}Coils, springs and zigzag curves
+do not really count to the ordinary when creating graphics. They are of some
+importance though when dealing with the creation of coilish connections. They
+can also be used for node connections which will be shown
+at the end of this chapter.
+
+The parameters especially for the \verb+coil+ variants are only easy to
+understand when keeping in mind that three dimensional helixes are dealt with,
+which are only projected onto the two dimensional paper plane. This will be
+elaborated on at the corresponding places.

+\tIndex{coilheight}\verb+coilheight+ is in contrast to \verb+coilwidth+ no
+length but only a factor, whereat the distance between two
+windings\index{winding} resp. jags is composed as follows:
+\begin{equation}dx = coilheight\cdot coilwidth \end{equation}
+
+As can be seen in the following example, not the same physical distance is
+yielded. This is caused by the internal three dimensional
+representation\index{three dimensional representation} of the coil; it is not
+seen under an angle of $90$° but $45$°. (section~\ref{subsec:pstcoil:coilaspect})

+\tIndex{coilarm}\tIndex{coilarmA}\tIndex{coilarmB}\verb+coilarm+ denotes the
+part of a straight line made left and right. Negative values are possible, but
+do not make a lot of sense as a rule. As can be gathered from the example, the
+coil is lenghtened by a negative value in this case, so that the part of a
+straight line is led back to the specified starting point resp. endpoint and
+consequently has a negative ``direction''{}. This parameter is not available for
+\CMD{psCoil}.

+\subsection{\texttt{coilaspect}}\label{subsec:pstcoil:coilaspect}
+% ---------------------------------------------------------------------------------------
+\tIndex{coilaspect}In section~\ref{subsec:pstcoil:coilheight} the three
+dimensional representation of the coil has been pointed out already. If it was
+regarded right-angled to its axis, the windings would not be recognizable. With
+\verb+coilaspect+ this ``perspective''{} can be influenced, which is only
+possible for the ``coil''{} variants of course. \verb+coilaspect=0+ yields a
+sine curve.
+
+\medskip\noindent
+\begin{LTXexample}[width=4cm]
+\begin{pspicture}(4,4.5)
+\pscoil(0,4)(4,4)
+\psset{coilwidth=0.75}

+
+
+% ---------------------------------------------------------------------------------------
+\subsection{\texttt{coilinc}}\label{subsec:pstcoil:coilinc}
+% ---------------------------------------------------------------------------------------
+\tIndex{coilinc}The curve is drawn with the \verb+lineto+ procedure of \PS,
+whereat \verb+coilinc+ specifies the rotation angle in the angular measure at
+which the next point is calculated. It has already been mentioned that the
+calculation is done as a three dimensional coil and is projected onto the two
+dimensional plane only in the end.
+
+\verb+coilinc+ does also not make sense for zigzag lines, so that this parameter
+again only is available for the \verb+coil+ variant. Large angles result in a
+polygon line, small angles in harmonic progressions with increased calculation
+effort.

+correspondly easy to use. Especially the \verb+linearc+ option can bring good
+results for \verb+\pszigzag+. The specification of the ``arm length''{} is not
+absolute here, since the line is principally ended in the geometrical middle and
+then led to the specified arm length.

+\section{Node connections}\label{sec:pstcoil:knotenverbindungen}

+Prerequisite for this macro is that \verb+pst-node+\tIndex{pst-node}
+is loaded, then the following node connections are
+available:
+%
+\begin{verbatim}
+\nccoil[<parameters>]{<nodeA>}{<nodeB>}
+\nccoil[<parameters>]{<arrows>}{<nodeA>}{<nodeB>}
+\nccoil*[<parameters>]{<nodeA>}{<nodeB>}
+\nccoil*[<parameters>]{<arrows>}{<nodeA>}{<nodeB>}
+\nczigzag[<parameters>]{<nodeA>}{<nodeB>}
+\nczigzag[<parameters>]{<arrows>}{<nodeA>}{<nodeB>}
+\nczigzag*[<parameters>]{<nodeA>}{<nodeB>}
+\nczigzag*[<parameters>]{<arrows>}{<nodeA>}{<nodeB>}
+\pccoil[<parameters>](<nodeA>)(<nodeB>)
+\pccoil[<parameters>]{<arrows>}(<nodeA>)(<nodeB>)
+\pccoil*[<parameters>](<nodeA>)(<nodeB>)
+\pccoil*[<parameters>]{<arrows>}(<nodeA>)(<nodeB>)
+\pczigzag[<parameters>](<nodeA>)(<nodeB>)
+\pczigzag[<parameters>]{<arrows>}(<nodeA>)(<nodeB>)
+\pczigzag*[<parameters>](<nodeA>)(<nodeB>)
+\pczigzag*[<parameters>]{<arrows>}(<nodeA>)(<nodeB>)
+\end{verbatim}
+
+These connections behave completely analogue to those dealt with the
+package \verb+pst-node+ so that
+no further explanations are needed here.
