+# Technical dimension lines in Tikz
+
+
+Dimension lines are drawn segments that indicate the measurement of a
+feature. The line has an arrow at both ends to show that the dimension
+displayed covers the entire span of that line. The direction of the line
+(vertical, horizontal or diagonal) shows the direction of the
+measurement. Dimension lines are kept outside of the object illustrated,
+typically connected to other lines that display the area where that
+measurement applies. This keeps the illustration clear.
+
+
+
+## Installation
+
+To install the `tkiz-dimline` package copy its directory to either to:
+
+- `$TEXHOME/tex/latex/`
+- `$TEXMFHOME/tex/latex/`
+- `~/texmf/tex/latex/`
+- `~/Library/texmf/tex/latex/`
+
+## Usage
+
+
+````Tex

+\item \verb"~/texmf/tex/latex/"

+\end{itemize}
+
+\section{Usage}
+
+\subsection{command}
+\begin{docCommand}{dimline}{\oarg{key path}\marg{start}\marg{end}\marg{label}}
+ Creates a new dimension line from \meta{start} to \meta{end} with
+ \meta{label}. An optional \meta{key path} can be used to customise the
+ dimension line.
+
+ This command has to be called within a \docAuxEnvironment*{tikzpicture}
+ environment.
+
+\end{docCommand}
+
+\subsection{options}
+\begin{docKey}{color}{=\meta{color}}{black}
+ Dimension line color.
+\end{docKey}
+\begin{docKey}{line style}{=\meta{style}}{not set}
+ Dimension line style, identical to {\PGF} line style.
+\end{docKey}
+\begin{docKey}{label style}{=\meta{style}}{not set}
+ Dimension label style, identical to {\PGF} label style.
+\end{docKey}
+
+\begin{docKey}{extension start length}{=\meta{size}}{1cm}
+ Length of the extention line at the start point.
+\end{docKey}
+
+\begin{docKey}{extension end length}{=\meta{size}}{1cm}
+ Identical to \refKey*{extension start length}, but for the end point.
+\end{docKey}
+
+\begin{docKey}{extension start angle}{=\meta{angle}}{-90}
+ Angle between the dimension line and the extention line at the start
+ point. You dont't want to change that value unless you really know what
+ you are doing. You would rather have a look to \refKey*{extension start
+ path} and \refKey*{extension end path}.
+\end{docKey}
+
+\begin{docKey}{extension end angle}{=\meta{angle}}{90}
+ Identical to \refKey*{extension start angle}, but for the end point.
+\end{docKey}
+
+\begin{docKey}{extension start style}{=\meta{style}}{not set}
+ Style for the extension line at the start point.
+\end{docKey}
+
+\begin{docKey}{extension end style}{=\meta{style}}{not set}
+ Identical to \refKey*{extension start style}, but for the end point.
+\end{docKey}
+
+\begin{docKey}{extension start path}{=\meta{path}}{not set}
+ Path (coordinates relative to the current
+ \docAuxEnvironment*{tkizpicture}) for the extension line at the start
+ point.
+\end{docKey}
+
+\begin{docKey}{extension end path}{=\meta{path}}{not set}
+ Identical to \refKey*{extension start path}, but for the end point.
+\end{docKey}
+
+
+\begin{docKey}{arrows}{=\meta{arrows spec}}{dimline-dimline}
+ Arrows used for the dimension line. \docAuxKey{dimline-dimline} is used
+ for standard arrows. Use \docAuxKey{dimeline reverse-dimline reverse} to
+ reverse the arrow heads.
+\end{docKey}
+
+
+
+\section{Examples}
+
+On following examples \docAuxCommand{helpgrid} is only used for a labeled
+grid. This not mandatory you can dicard this line. See source of this
+documentation to see how \docAuxCommand{helpgrid} command is defined.
+
+
+
+\subsection{Basic usage}
+
+This is a very simple usage. It just draws a dimension line (using default
+values) between 2 points with a label on it. Note that the dimension starts
+at the border of the side tick mark, not at the end of the arrow.
+
+\begin{exampleB}{}
+ \begin{tikzpicture}[spy using outlines={circle, magnification=25, size=6cm,
+ connect spies}]
+ \helpgrid{-1}{-1}{5}{4}
+ \draw[line width=0.01,color=red] plot[mark=+] coordinates{(3,3)} {};
+ \draw[line width=0.01,color=green] plot[mark=x] coordinates{(3,3)} {};
+ \dimline[line style = {line width=0.5}]{(0,0)}{(3,3)}{Label};
+ \spy [blue] on (2.975,2.975) in node [fill=white] at (6.5,1.5);
+ \end{tikzpicture}
+\end{exampleB}
+
+
+\subsection{Reverse arrows}
+
+Sometimes, shuch as for very small dimensions, you need to reverse the
+arrows. You can then use a \docAuxKey{dimeline reverse} arrow.
+
+\begin{exampleB}{}
+ \begin{tikzpicture}[spy using outlines={circle, magnification=25, size=6cm,
+ connect spies}]
+ \helpgrid{-1}{-1}{5}{4}
+ \draw[line width=0.01,color=red] plot[mark=+] coordinates{(3,3)} {};
+ \draw[line width=0.01,color=green] plot[mark=x] coordinates{(3,3)} {};
+
+ \dimline[line style = {line width=0.5,
+ arrows=dimline reverse-dimline reverse}]{(0,0)}{(3,3)}{Label};
+ \spy [blue] on (3.025,3.025) in node [fill=white] at (6.5,1.5);
+ \end{tikzpicture}
+\end{exampleB}
+
+\subsection{Styling your dimension lines}
+
+You can customize your dimension lines like any other \TikZ{} environment.
+\begin{exampleB}{}
+ \begin{tikzpicture}[scale=0.5]
+ \helpgrid{-1}{-1}{4}{7}
+ \draw (0,0) -- (0,4) -- (.5,4) -- (.5,5) -- (1.,5) -- (1.,4) -- (1.5,4) -- (1.5,0)
+ -- cycle;
+ \dimline[color=blue,
+ extension start length=-0.25, extension end length=-0.25]{(2.75,0)}{(2.75,4)}{4.0};
+ \dimline[color=red,
+ line style={arrows=dimline reverse-dimline reverse},
+ label style={above=0.8ex,font=\tiny},
+ extension start length=1,
+ extension end length=1]{(0.5,5.6)}{(1.0,5.6)}{0.5};
+ \end{tikzpicture}
+\end{exampleB}
+
+
+\subsection{Complex extension lines}
+
+This example shows you how to use both a \docAuxKey{extension start path}
+and \docAuxKey{extension end path}. This is useful if you want to enlarge a
+small dimension area.
+
+\begin{exampleB}{}
+ \begin{tikzpicture}[scale=0.5]
+ \helpgrid{-1}{-1}{4}{7}
+ \draw (0,0) -- (0,4) -- (.5,4) -- (.5,5) -- (1.,5) -- (1.,4) -- (1.5,4) -- (1.5,0)
+ -- cycle;
+
+ \draw[color=red] node (A) at (2.5,0) {} node [yshift=1ex,xshift=-1ex]
+ at (A) {\tiny{A}};
+ \dimline[color=blue,
+ line style = {line width=0.7},
+ extension start length=-0.24,
+ extension end length=-0.24] {(A)}{($ (A) + (0,4) $)}{4.0};
+ \dimline[label style={above=0.5ex, fill=blue!10,},
+ extension start path = {(0,6) (0,5.7) (0.5,5.4) (0.5,5.05)},
+ extension start style = { green },
+ extension end path = {(1.5,6) (1.5,5.7) (1,5.4) (1,5.05)},]
+ {(0,6)}{(1.5,6)}{0.5};
+ \draw[color=red,line width=0.01] plot[mark=x] coordinates{(A)} {};
+ \end{tikzpicture}
+\end{exampleB}
