+# TikZ Library for Structural Analysis
+## Purpose
+
+At university it is always a very time consuming work to create new
+assignments, and tests; especially when those tasks include drawing graphics.
+
+In the field of structural engineering those small structures are a key part
+for teaching. For this reason I developed, in cooperation with the 
+[Institute for Structural Analysis](https://www.tugraz.at/institute/ifb/home/) 
+at the [Graz University of Technology](http://tugraz.at/), 
+a TikZ library for Structural Analysis.
+
+With the package `stanli`, 2D and 3D structures can be created. In the following article only the 2D library will be discussed, but the principles and methods are the same for 3D structures.
+
+## Principles
+
+TikZ is a very powerful tool; however, unfortunately not everyone is used to this part of LaTeX. 
+Therefore, in addition to the creation of the library the second goal was to keep the usage as simple as possible. So that:
+
+* anyone can use this library without (deeper) knowledge in TikZ
+* skilled users can easily modify and customise the code
+* the principle of this library can be used for any other library
+
+## Getting Started
+### LaTeX Environment
+
+Like every TikZ graph, needs also this library the
+
+```  \begin{tikzpicture}
+       ...
+     \end{tikzpicture}```
+
+environment.
+
+### Elements
+#### Basic Commands
+
+The library provides 10 different commands:
+
+* ``\point``
+* ``\beam``
+* ``\support``
+* ``\hinge``
+* ``\load`` or ``\lineload`` and ``\temperature``
+* ``\internalforces``
+* ``\dimensioning``
+* ``\influenceline``
+* ``\notation``
+* ``\addon``
+
+For each element (command) are different options available. Obligatory options
+are marked with {curley brackets} and optional values are marked with [square
+brackets]. The first type is a must have criteria. In contrast, the optional
+input is not required to be entered.
+
+An easy example is the following single force:
+
+```\load{type}{insertion point}[rotation][length or included angle][loaddistance];```
+
+### Manual
+
+More specific information about the elements and their options can be found in
+the manual. The manual is written in English. Section 1 provides a table
+with all elements and options; furthermore, the code is also given for each
+picture in the manual.
+
+### Examples
+
+The easiest way to create a structure is the list above, starting with ``\point``
+and ending with ``\addon``.
+
+The following examples shall give a first impression how drawings can be
+generated. In the manual the example is explained in more detail.
+
+#### 2D Simplified Roof
+
+By using the library ``stanli``, the following graph can be created
+in a very short time:
+
+```
+\begin{tikzpicture}
+     \scaling{.65};
+
+     \point{a}{0}{1};
+     \point{b}{3}{1};
+     \point{c}{11}{3};
+     \point{d}{19}{1};
+     \point{e}{22}{1};
+     \point{f}{3}{0};
+     \point{g}{11}{-2};
+     \point{h}{19}{0};
+
+     \beam{1}{a}{b}[0][1];
+     \beam{1}{b}{c}[1][1];
+     \beam{1}{c}{d}[1][1];
+     \beam{1}{d}{e}[1][0];
+     \beam{1}{f}{b};
+     \beam{1}{d}{h};
+     \beam{2}{f}{g};
+     \beam{2}{g}{h};
+     \beam{2}{g}{c};
+
+     \support{1}{f};
+     \support{2}{h};
+
+     \hinge{1}{f};
+     \hinge{1}{h};
+     \hinge{1}{g};
+     \hinge{2}{c}[b][d];
+
+     \lineload{2}{a}{b}[1][1][.5];
+     \lineload{2}{b}{c};
+
+     \dimensioning{1}{a}{b}{-2.5}[$3,0$];
+     \dimensioning{1}{b}{c}{-2.5}[$8,0$];
+     \dimensioning{1}{c}{d}{-2.5}[$8,0$];
+     \dimensioning{1}{d}{e}{-2.5}[$3,0$];
+     \dimensioning{2}{f}{a}{-1}[$1,0$];
+     \dimensioning{2}{g}{f}{-1}[$2,0$];
+     \dimensioning{2}{a}{c}{-1}[$2,0$];
+
+     \influenceline{a}{e}{3}[.3];
+
+     \notation{1}{a}{$1$}[left];
+     \notation{1}{b}{$2$}[below right=2mm];
+     \notation{1}{c}{$3$};
+     \notation{1}{d}{$4$}[above];
+     \notation{1}{e}{$5$}[above];
+     \notation{1}{f}{$6$}[left=2mm];
+     \notation{1}{g}{$7$}[below=2mm];
+     \notation{1}{h}{$8$}[right=2mm];
+     \notation{4}{f}{g}[$S$];
+
+   \end{tikzpicture}
+```

+
+
+#### 3D Support Construction
+
+By using the library ``stanli``, the following 3D structure can be created in a very short time with few lines of code:
+
+```
+  \setcoords{-25}{10}[1][1.2]
+  \setaxis{2}
+  %\showpoint
+  \begin{tikzpicture}[coords]
+
+     \dpoint{a}{0}{0}{0};

+     \dpoint{i}{9}{3}{0};
+     \dpoint{j}{12}{3}{0};
+
+     \daxis{1}{a};
+

+     \ddimensioning{yx}{e}{j}{13}[$3~m$];
+
+     \dnotation{1}{f}{$q=10~kN/m$}[above left=3mm];
+     \dnotation{1}{b}{$A$}[below left];
+     \dnotation{1}{h}{$C$}[right=2mm];
+     \dnotation{1}{d}{$B$}[below left];

+\chapter{Introduction}
+\label{chap:einleitung}
+
+The following work is a manual for a library of symbols for structural analysis. This library is based on the PGF/\tikzsym environment. Accordingly, commands from these packages are used. Nevertheless, comprehensive knowledge of \tikzsym is not necessary in order to use this library. If the referenced commands in this manual are not enough for the interested reader, the \tikzsym manual from Till Tantau is suggested.
+
+% Die folgende Arbeit stellt ein Manual für die im Bachelor Projekt erstellte Bibliothek von baustatischen Symbolen dar. Diese Bibliothek wurde mit dem System PGF/\tikzsym erstellt und enthält dementsprechende Befehle aus den betreffenden Packages. Jedoch ist eine umfassende Kenntnis von \tikzsym nicht notwendig um die Bibliothek bedienen zu können. Falls die hier erwähnte Befehle nicht ausreichen, wird dem interessierten Leser das \tikzsym Manual von Till Tantau nahe gelegt. %\cite{script:pgf}

+
+\section{How to read this manual?}
+
+This manual describes the use of the library for symbols for structural analysis. To ensure an easy use of the elements and to keep the clarity, this manual follows the structure of the ``\tikzsym and PGF Manual'' and starts with the essential components (command list, elements) and subsequently deals with the ``whole schmear''. Finally, everything is repeated and summarized in form of a brief tutorial.  
+
+If the required packages have not yet been installed, you should read before starting, the installation chapter.
+
+\subsection{A few explanations} All images in this manual were created with
+\tikzsym or the element library. The code used for this, is specified for each
+image.

+\subsection{Additional help}
+
+Is the manual not enough, occur some ambiguities or some \tikzsym commands are unclear, please have a look in the ``\tikzsym and PGF Manual'' von Till Tantau.
+
+Should you have any further questions, please do not hesitate to contact me. 
+
+\section{Installation}
+\label{sec:Installation}
+
+Actually, we can hardly speak of an installation since only the necessary package \lstinline|\usepackage{structuralanalysis}| must be installed.
+
+Is the package installed or the style file i stored in the main file folder, so the library can be imported by \lstinline|\usepackage{structuralanalysis}|, as a following example shows:
+

+	BCOR20mm,           % correction
+	twoside,            % changes to a two-page-layout (alternatively: oneside)
+	halfparskip,        % insert an empty line between two paragraphs (alternatively: parskip, ...)
+	openright,          % chapter starts on the right page

+\end{lstlisting}
+
+\section{Additional necessary packages}
+\label{sec:WeitereNotwendigePackages}
+
+To use all commands and options of \tikzsym, possibly some packages need to be reloaded. These missing files (or their names) appear in the error log, when you convert the file. However, for the package described in this manual, it is sufficient to use the library and the \tikzsym standard commands.

+
+\section{General information about the elements}
+\label{sec:AllgemeinesZuDenElementen}
+
+\subsection{Order}
+\label{sec:Reihenfolge}
+
+The library provides a number of standard elements available to the user. For example, bearings, joints, forces, etc. Since \tikzsym displayes those elements at the bottom which are entered first, it must be ensured that the element insert in the correct order. The following order is recommended:
+
+\begin{enumerate}
+	\item Points \lstinline|\point|
+	\item Beams and bars \lstinline|\beam|
+	\item Supports and bearings \lstinline|\support|
+	\item Joints \lstinline|\hinge|
+	\item Force and temperature \lstinline|\load| respectively \lstinline|\lineload| and \lstinline|\temperature|
+	\item Internal forces \lstinline|\internalforces|
+	\item Dimensioning \lstinline|\dimensioning|
+	\item Range of the influence line \lstinline|\influenceline|
+	\item Labeling \lstinline|\notation|
+	\item Additional symbols \lstinline|\addon|
+\end{enumerate}
+
+\subsection{Input}
+\label{sec:Eingabe}
+
+In addition to the correct order also the correct input for the elements matters.
+
+Basically, one can distinguish between the mandatory input $\{~\}$ and the optional input $[~]$. The first values must be entered compulsory. By contrast, nothing has to be entered for the optional input. Additional features (eg. rotation) can be activated when entering optional parameters.
+
+For illustration a small example of a single force
+
+\begin{lstlisting}
+	\load{type}{insertion point}[rotation][length or included angle][loaddistance];
+\end{lstlisting} 
+
+
+When entering size values the base unit is always predefined in $[cm]$.  Percentage values $\%$ are always specified as decimal values; for example, $100\% = 1.0 $ and $ 10 \% $ corresponds to $ 0.1 $.
+
+Another important note is, that every \tikzsym command has to be completed with an semicolon ``;''. If this semicolon is not set, the command can not be performed, this leads finally to an error message by the compilation.

+
+
+\leftskip=7mm In order to be able, to place elements, points must be defined previously. For the labeling a short and precise name should be chosen. Because other elements will reference back to these points, in the later stages of the construction. Since \tikzsym uses Cartesian coordinates, this must be entered in accordance with the coordinate system. This means that is first entry corresponds to the x-coordinate and the second to the y-coordinate.

+\lstinline[emph={beam}]|\beam{type}{initial point}{end point}[rounded initial point][rounded end point];|

+
+\leftskip=7mm The library includes several types of beams and bars. These are determined by the type. To construct such a beam or bar, two points must first be defined, the starting point and the end point. Furthermore, is an optional available to round the ends of the bars. $[0]$ or no entry means the corresponding end of the beam is not rounded, $[1]$ the end is rounded. This option is especially needed when multiple bars meet with different angles.

The entries are made as repeatedly shown above. First, the start and end points must be determined. Thereafter, the start and end values must be entered. Optional the parabola down can be enter. If there is no entry or the entry is equal to $[0]$, than it is a linear function. Also optionally, the color can be determined. Here the most common colors are available and addressed with the color name. The last optional parameter is used to edit the parabola down and if necessary to adapt the plot to another function.

+\subsection{Start of the consturction}
+\label{sec:StartDerKonstruktion}
+
+In order to create the desired roof structure, a file has to be created first. In this example, it is a \LaTeX ~file. However, the library can also be used with \TeX ~and ~Con\TeX files.
+
+\begin{lstlisting}
+\documentclass{scrreprt} % say
+
+\usepackage{structuralanalysis}
+
+\begin{document}
+	\begin{tikzpicture}
+		% here we construct our structure
+	\end{tikzpicture}
+\end{document}
+\end{lstlisting}
+
+\subsection{First steps}
+\label{sec:ErsteSchritte}
+
+First, we have to specify corresponding points with the command \lstinline|\point|. On this basis, the remaining library elements are placed. Since the points are not shown in the graph, it is recommended to create a helping grid, to predict the distances and sizes. The basic size of a grid element is $1~cm $ by $1 ~cm $.
+
+\begin{minipage}[c]{0.65\linewidth}
+	\begin{tikzpicture}[framed]
+			\draw[help lines] (0,0) grid (9,1);
+	\end{tikzpicture}
+\end{minipage}
+\begin{minipage}{0.35\linewidth}\begin{lstlisting}
+\begin{tikzpicture}
+	\draw[help lines] 
+		(0,0) grid (9,1); 
+\end{tikzpicture}\end{lstlisting}\vspace{-7mm}
+\end{minipage}
+
+Here, it is obvious that the roof structure with a width of $ 22 ~cm $ does not fit on this page. In order not to change all the dimensions recalculating all distances, the command \lstinline|scaling| can be used. Hereby, the distances are scaled depending on the desired scaling factor. However, the symbols and the entries remain unchanged. 
+
+Note, since the help grid is a function of \tikzsym, the scaling command can not be used for the guides. If we recalculate the size of the grid we get following situation:
+
+\begin{minipage}[c]{0.65\linewidth}
+\begin{tikzpicture}[framed]
+	\scaling{.45};
+	\draw[help lines,step=.45] (0,-.9) grid (9.9,1.35);
+\end{tikzpicture}
+\end{minipage}
+\begin{minipage}{0.35\linewidth}\begin{lstlisting}
+\begin{tikzpicture}
+	\scaling{.45};
+	\draw[help lines,step=.45]
+		(0,-.9) grid (9.9,1.35);
+\end{lstlisting}\vspace{-7mm}
+\end{minipage}
+
+Now the points of the structure can be easily entered. Since the points, as mentioned above, are not visible, they are identified by illustration as orange dots.
+
+\begin{minipage}[c]{0.65\linewidth}
+\begin{tikzpicture}[framed]
+	\scaling{.45};
+	\draw[help lines,step=.45] (0,-.9) grid (9.9,1.35);
+
+	\point{a}{0}{1};
+	\point{b}{3}{1};
+	\point{c}{11}{3};
+	\point{d}{19}{1};
+	\point{e}{22}{1};
+	\point{f}{3}{0};
+	\point{g}{11}{-2};
+	\point{h}{19}{0};
+	
+	\filldraw [orange] (a) circle (2pt);
+	\filldraw [orange] (b) circle (2pt);
+	\filldraw [orange] (c) circle (2pt);
+	\filldraw [orange] (d) circle (2pt);
+	\filldraw [orange] (e) circle (2pt);
+	\filldraw [orange] (f) circle (2pt);
+	\filldraw [orange] (g) circle (2pt);
+	\filldraw [orange] (h) circle (2pt);
+	
+\end{tikzpicture}
+\end{minipage}
+\begin{minipage}{0.35\linewidth}\begin{lstlisting}
+	\point{a}{0}{1};
+	\point{b}{3}{1};
+	\point{c}{11}{3};
+	\point{d}{19}{1};
+	\point{e}{22}{1};
+	\point{f}{3}{0};
+	\point{g}{11}{-2};
+	\point{h}{19}{0};
+\end{lstlisting}\vspace{-7mm}
+\end{minipage}
+
+\subsection{Roof structure}
+\label{sec:Dachdecken}
+
+After the foundation stone was laid by the points, we can start to connect the points with  beams and bars. In the library bars are with or without characteristics fiber available. With the command \lstinline|\beam| they can be brought to `` paper''.
+
+\begin{minipage}[c]{0.65\linewidth}
+\begin{tikzpicture}[framed]
+	\scaling{.45};
+	\draw[help lines,step=.45] (0,-.9) grid (9.9,1.35);
+	
+	\point{a}{0}{1};
+	\point{b}{3}{1};
+	\point{c}{11}{3};
+	\point{d}{19}{1};
+	\point{e}{22}{1};
+	\point{f}{3}{0};
+	\point{g}{11}{-2};
+	\point{h}{19}{0};
+	
+	\filldraw [orange] (f) circle (4pt);
+	\filldraw [orange] (g) circle (4pt);
+	\filldraw [orange] (h) circle (4pt);
+		
+	\beam{1}{a}{b}[0][1];
+	\beam{1}{b}{c}[1][1];
+	\beam{1}{c}{d}[1][1];
+	\beam{1}{d}{e}[1][0];
+	\beam{1}{f}{b};
+	\beam{1}{d}{h};
+	\beam{2}{f}{g};
+	\beam{2}{g}{h};
+	\beam{2}{g}{c};
+		
+\end{tikzpicture}
+\end{minipage}
+\begin{minipage}{0.35\linewidth}\begin{lstlisting}
+	\beam{1}{a}{b}[0][1];
+	\beam{1}{b}{c}[1][1];
+	\beam{1}{c}{d}[1][1];
+	\beam{1}{d}{e}[1][0];
+	\beam{1}{f}{b};
+	\beam{1}{d}{h};
+	\beam{2}{f}{g};
+	\beam{2}{g}{h};
+	\beam{2}{g}{c};
+\end{lstlisting}\vspace{-7mm}
+\end{minipage}
+
+If the edges are not rounded, as it has been happened above, there is no smooth transition of the beams (see orange dots). However, at these points it does not matter, because in a later phase joints are placed above.
+
+\subsection{Bearings and joints}
+\label{sec:LagerUndGelenke}
+
+In order to provide more flexibility, and to keep the number of macros as low as possible, their are own commands available for the bearings and the joints. Bearings are built with the command \lstinline|\support|. However, the corresponding joint must independently created with the command \lstinline|\hinge|. This allows to combine different bearings with different joints. The important thing is always that the bearing has to be created first and only then the joints should be implemented. This is necessary, because \tikzsym puts the recently drawn figures on the top.
+
+\begin{minipage}[c]{0.65\linewidth}
+\begin{tikzpicture}[framed]
+	\scaling{.45};
+	\draw[help lines,step=.45] (0,-.9) grid (9.9,1.35);
+	
+	\point{a}{0}{1};
+	\point{b}{3}{1};
+	\point{c}{11}{3};
+	\point{d}{19}{1};
+	\point{e}{22}{1};
+	\point{f}{3}{0};
+	\point{g}{11}{-2};
+	\point{h}{19}{0};
+		
+	\beam{1}{a}{b}[0][1];
+	\beam{1}{b}{c}[1][1];

+\begin{minipage}{0.35\linewidth}\begin{lstlisting}
+	\support{1}{f};
+	\support{2}{h};
+\end{lstlisting}\vspace{-7mm}
+\end{minipage}
+
+After the bearings are created, we can start with drawing the joints. As with most elements the library provides a set of different types of joints. For instance, the point $c$ is described by a half-joint.
+

+\subsection{Snow on the roof}
+\label{sec:SchneeAmDach}
+
+With the insertion of the joints, the construction is completed and can now be loaded. Besides single loads \lstinline|\load| are line loads \lstinline|\lineload| and temperature loads \lstinline|\temperature| available.

+\section{General information about the elements}
+\label{sec:3dAllgemeinesZuDenElementen}
+\subsection{Order}
+\label{sec:3dReihenfolge}
+
+The library provides a number of standard elements available to the user. For example, bearings, joints, forces, etc. Since \tikzsym displayes those elements at the bottom which are entered first, it must be ensured that the element insert in the correct order. The following order is recommended:
+
+\begin{enumerate}
+	\item Points \lstinline|\dpoint|
+	\item Beams and bars \lstinline|\dbeam|
+	\item Axis \lstinline|\daxis|
+	\item Supports and bearings \lstinline|\dsupport|
+	\item Joints \lstinline|\dhinge|
+	\item Force and moments \lstinline|\dload| respectively \lstinline|\dlineload|
+	\item Internal forces \lstinline|\dinternalforces|
+	\item Dimensioning \lstinline|\ddimensioning|
+	\item Labeling \lstinline|\dnotation|
+	\item Additional symbols \lstinline|\daddon|
+\end{enumerate}
+
+\subsection{Input}
+\label{sec:3dEingabe}
+
+In addition to the correct order also the correct input for the elements matters.
+
+Basically, one can distinguish between the mandatory input $\{~\}$ and the optional input $[~]$. The first values must be entered compulsory. By contrast, nothing has to be entered for the optional input. Additional features (eg. rotation) can be activated when entering optional parameters.
+
+For illustration a small example of a single force
+
+\begin{lstlisting}
+	\dload{type}{insertion point}[rotation A][rotation B][load length][load distance];
+\end{lstlisting} 
+
+When entering size values the base unit is always predefined in $[cm]$.  Percentage values $\%$ are always specified as decimal values; for example, $100\% = 1.0 $ and $ 10 \% $ corresponds to $ 0.1 $.
+
+Another important note is, that every \tikzsym command has to be completed with an semicolon ``;''. If this semicolon is not set, the command can not be performed, this leads finally to an error message by the compilation.
+
+\subsection{Planes and spatial elements}
+\label{sec:3dEbenenUndRaumlicheElemente}
+
+In the 3D case, a specification is made between elements on a plane and spatial elements. The first kind of elements are parallel to a coordinate plan, i.e. parallel to $xy$-plane, $xz$-plane or $yz$-plane. Beside those three coordinate planes, \tikzsym also recognizes the planes $yx$, $zx$ and $zy$. Hereby, the difference is that the orientation of the object will change.
+
+All elements are called spatial elements, if there are no parallels to the planes mentioned above. The orientation of those elements is based on spherical coordinates or with corresponding rotations. Using spherical coordinates, the first entry always describes the angle form the zenith to the equator, the second one the angle around the equator.
+
+\subsection{TikZ Environment}
+\label{sec:3dTikZUmgebung}
+
+To ensure a adequate view for the construction of the structure, a initial coordinate system has to be loaded in the \tikzsym environment. This can be done with the option \lstinline|[coords]| an looks like this:
+
+\begin{lstlisting}
+	\begin{tikzpicture}[coords]
+
+	\end{tikzpicture
+\end{lstlisting}\vspace{-7mm}
+%
+With the command \lstinline|\setcoords| (see \ref{sec:3dsetcoords}), the orientation of the coordinates can be modified.

Because other elements will reference back to these points, in the later stages of the construction. Since \tikzsym uses Cartesian coordinates, this must be entered in accordance with the coordinate system. This means that is first entry corresponds to the x-coordinate and the second to the y-coordinate and the third to the z-coordinate. Because, the points are not shown in the drawing, with the command \lstinline|\showpoint| (see \ref{sec:3dshowpoint}) there is the possibility to show the labels of the points.

+\leftskip=7mm The library includes several types of beams and bars. These are determined by the type. To construct such a beam or bar, two points must first be defined, the starting point and the end point. Furthermore, is an optional available to round the ends of the bars. $[0]$ or no entry means the corresponding end of the beam is not rounded, $[1]$ the end is rounded. This option is especially needed when multiple bars meet with different angles.

To change the axis names themselves, the command \lstinline|\setaxis| has to be used (see \ref{sec:3dsetaxis}).

+Type $3$ describes a local axis in space. Contrary to type $2$ not the plane but but the rotations is specified. With rotation $A$ and $B$, the position of the local axis system is defined. Both angles describe the spherical coordinates originating the insert point. With the rotation angles $1$, $2$ and $3$ the local coordinate system is rotated. With angle $1$ the axis is rotated around the $z$-axis. With angle $2$ the rotation around the $y$-axis is defined. And with angle $3$ the rotation of the not yet turned $z$-axis is specified.

+\section{Structural design}
+\label{sec:3dTragwerkskonstruktion}
+
+In this tutorial, the basic principles of designing 3D structures with \tikzsym and ``stanli'' are treated. Step by Step, a structural design should be created. The final result is shown below.

+\subsection{Start of the consturction}
+\label{sec:3dStartDerKonstruktion}
+
+
+In order to create the desired structural design, a file has to be created first. In this example, it is a \LaTeX ~file. However, the library can also be used with \TeX ~and ~Con\TeX files.
+
+\begin{lstlisting}
+\documentclass{scrreprt}
+
+\usepackage{stanli}
+
+\begin{document}
+	\begin{tikzpicture}[corrds]
+		% here we construct our structure
+	\end{tikzpicture}
+\end{document}
+\end{lstlisting}\vspace{-7mm}
+
+\subsection{Preparation}
+\label{sec:3dVorbereitung}
+
+Before starting the construction, relevant settings has to be made in advance. Among others, a new coordinate system with \lstinline|\setcoords| will be introduced. Likewise, the labeling of the global and local axes can be changed.
+
+\begin{lstlisting}
+\setcoords{-25}{10}[1][1.2]
+\setaxis{2}
+\begin{tikzpicture}[corrds]
+	% here we construct our structure
+\end{tikzpicture}
+\end{lstlisting}\vspace{-7mm}
+
+\subsection{Placing points}
+\label{sec:3dPunkteSetzen}
+
+First, we have to specify corresponding points with the command \lstinline|\dpoint|. On this basis, the remaining library elements are placed. Since the points are not shown in the graph, it is recommended to display the point labels during the construction phase. This can be done with the command \lstinline|\showpoint|.

+\subsection{The construction}
+\label{sec:3dDieKonstruktion}
+
+After the foundation stone was laid by the points, we can start to connect the points with beams and bars. In the library different beams and bars are available. With the command \lstinline|\dbeam| they can be brought to `` paper''.

+\subsection{Axes for the overview}
+\label{sec:3dAchsenfurUbersicht}
+
+
+In order not to lose the overview, it is advisable to display a global axis system already at the beginning. The local axes can be added later.

+\subsection{Supports and joints}
+\label{sec:3dLagerUndGelenke}
+\vspace*{-5mm}
+In order to provide more flexibility, and to keep the number of macros as low as possible, their are own commands available for the supports and the joints. Supports are built with the command \lstinline|\dsupport|. However, the corresponding joint must independently created with the command \lstinline|\dhinge|. This allows to combine different bearings with different joints. The important thing is always that the bearing has to be created first and only then the joints should be implemented. This is necessary, because \tikzsym puts the recently drawn figures on the top.

+\subsection{Loads}
+\label{sec:3dSchneeAmDach}
+\vspace*{-5mm}
+
+With the insertion of the joints, the construction is completed and can now be loaded. Besides single loads \lstinline|\dload| are line loads \lstinline|\dlineload| available. Because the loads are not parallel to one of the main coordinate plains, a line load in space (type $5$) has to be used.
