The following file (which comes from an article in the TeXnische Komödie about the schulma-physik package), say subfile.tex, compiles like a charm: \documentclass{article} \usepackage[compatibility]{circuitikz} \usetikzlibrary{circuits.ee.IEC} \makeatletter % Ergänzungen von Schaltzeichenformen auf der Grundlage von pgflibraryshapes.gates.ee.IEC.code.tex \pgfdeclareshape{leere diode} {% \inheritsavedanchors[from=rectangle ee]% \inheritanchor[from=rectangle ee]{center}% \inheritanchor[from=rectangle ee]{north}% \inheritanchor[from=rectangle ee]{south}% \inheritanchor[from=rectangle ee]{east}% \inheritanchor[from=rectangle ee]{west}% \inheritanchor[from=rectangle ee]{north east}% \inheritanchor[from=rectangle ee]{north west}% \inheritanchor[from=rectangle ee]{south east}% \inheritanchor[from=rectangle ee]{south west}% \inheritanchor[from=rectangle ee]{input}% \inheritanchor[from=rectangle ee]{output}% \inheritanchorborder[from=rectangle ee]% % \backgroundpath{ \pgf@process{\pgfpointadd{\southwest}{\pgfpoint{\pgfkeysvalueof{/pgf/outer xsep}}{\pgfkeysvalueof{/pgf/outer ysep}}}} \pgf@xa=\pgf@x \pgf@ya=\pgf@y \pgf@process{\pgfpointadd{\northeast}{\pgfpointscale{-1}{\pgfpoint{\pgfkeysvalueof{/pgf/outer xsep}}{\pgfkeysvalueof{/pgf/outer ysep}}}}} \pgf@xb=\pgf@x \pgf@yb=\pgf@y % Move tip back a little bit \advance\pgf@xb by-.5\pgflinewidth % Triangle triangle: \pgfpathmoveto{\pgfqpoint{\pgf@xa}{\pgf@ya}} \pgfpathlineto{\pgfqpoint{\pgf@xa}{\pgf@yb}} \pgf@yc=.5\pgf@ya \advance\pgf@yc by .5\pgf@yb \pgfpathlineto{\pgfqpoint{\pgf@xb}{\pgf@yc}} \pgfpathclose }% \beforebackgroundpath{ { \pgf@process{\pgfpointadd{\southwest}{\pgfpoint{\pgfkeysvalueof{/pgf/outer xsep}}{\pgfkeysvalueof{/pgf/outer ysep}}}} \pgf@ya=\pgf@y \pgf@process{\pgfpointadd{\northeast}{\pgfpointscale{-1}{\pgfpoint{\pgfkeysvalueof{/pgf/outer xsep}}{\pgfkeysvalueof{/pgf/outer ysep}}}}} \pgf@xb=\pgf@x \pgf@yb=\pgf@y \pgf@yc=.5\pgf@ya \advance\pgf@yc by.5\pgf@yb \pgfusepathqstroke \pgftransformshift{\pgfqpoint{\pgf@xb}{\pgf@yc}} \pgf@yc=.5\pgf@yb \advance\pgf@yc by-.5\pgf@ya \pgftransformscale{\pgf@sys@tonumber{\pgf@yc}} \pgfkeysvalueof{/pgf/generic diode IEC/before background} } }% } \makeatother \tikzset{ leere diode graphic/.style={ circuit symbol open, circuit symbol size=width 1.25 height 1.25, transform shape, shape=leere diode, /pgf/generic diode IEC/before background={ \pgfpathmoveto{\pgfqpoint{0pt}{-1pt}} \pgfpathlineto{\pgfqpoint{0pt}{1pt}} \pgfusepathqstroke }, }, } \begin{document} \begin{tikzpicture}[circuit ee IEC,circuit symbol unit=5.5pt] \tikzset{set diode graphic=leere diode graphic}\draw (0,0) to[diode] (1,0); \end{tikzpicture} \end{document} But if it is compiled via another file—say, mainfile.tex—using the standalone package: \documentclass{article} \usepackage[subpreambles]{standalone} \begin{document} \input{subfile.tex} \end{document} the second compilation fails with the following error: (./subfile.tex ! Undefined control sequence. \pgf@sh@bg@leere diode ->\pgf @process{\pgfpointadd {\southwest }{\pgfpoint ... l.77 ... diode graphic}\draw (0,0) to[diode] (1,0) ; ? Although the mainfile.sta file contains the entire preamble of the subfile.tex file—including the \makeatletter and \makeatother commands—it appears that the @ character is not treated as a letter. Do you understand why, and do you know how to solve this problem?

This post is similar to this one, but not exactly the same... With the following code: \documentclass{article} \usepackage{amsmath} \usepackage{tikz} \usetikzlibrary{matrix} \setlength{\fboxsep}{0pt} \begin{document} \[ \begin{tikzpicture} \matrix (magic) [ matrix of math nodes, nodes={circle,draw=magenta,minimum size=1cm}, left delimiter=(, right delimiter=) ] { 1 \\ & 1 \\ & & \ddots \\ & & & \fbox{$\ddots$} \\ & & & & 1 \\ }; \draw[teal,dashed] (magic-1-1.center) -- (magic-5-5.center); \end{tikzpicture} \] \end{document} What I want was the following: only typeset three dots, thus \Ddots with nicematrix was not so flexible; I want the "slope" of \ddots was parallel with the teal,dashed line; I want to ellnimate the extra height of the bounding box of \ddots(why?It looks not good...) It recalled the classical \rvdots here, and we know: $ latexdef \ddots \ddots: macro:->\protect \ddots \ddots : macro:->\mathinner {\mkern 1mu\raise 7\p@ \vbox {\kern 7\p@ \hbox {.}}\mkern 2mu \raise 4\p@ \hbox {.}\mkern 2mu\raise \p@ \hbox {.}\mkern 1mu} I guessed slightly modify the commands could help? Any suggestions? \makeatletter % \DeclareRobustCommand{\rvdots}{% % \vbox{ % \baselineskip4\p@\lineskiplimit\z@ % \kern-\p@ % \hbox{.}\hbox{.}\hbox{.} % }} \DeclareRobustCommand{\rddots}{% \mathinner {% \mkern 1mu\raise 7\p@% \vbox{\kern 1\p@ \hbox {.}}% \mkern 0.4mu \raise 4\p@ \hbox {.}% \mkern 0.4mu\raise \p@ \hbox {.}% \mkern 1mu% }% } \makeatother Edit1 If I zoomed in with with cfr's answer: \makeatletter \newcommand\exddots {% \mathinner {% \mkern 1mu\raise 3.5\p@ % 7 -> 3.5 \vbox {\kern 0\p@ \hbox {.}}% 7 -> 0 \mkern 2mu \raise -0.5\p@ \hbox{.}% 4 -> -0.5 \mkern 2mu \raise -4\p@ \hbox{.}% \p@ -> -4 \mkern 1mu }% } \makeatother Edit2 Just to show the example of cfr's comment: Is the content or, at least, the size of the content in the matrix fixed? because the angle of the diagonal obviously will vary if that varies. so unless you want this only as a one-off, you maybe need to think about how this should work. should \exddots really look different each time and different from any use in maths mode? or do you want to fix the matrix dimensions to keep the angle constant? or ...? I don't think it will look so good if the dots look different in different cases. at least, that is not how it usually would work in latex? \documentclass{article} \usepackage{amsmath} \usepackage{nicematrix} \usepackage{tikz} % \usepackage{kpfonts-otf} \begin{document} \[ \begin{pNiceMatrix} 3 & & & \\ & 555 & & \\ & & \ddots & \\ & & & 66666 \CodeAfter \tikz{ \draw[teal, ultra thin] (1-1.center) -- (4-4.center); \draw[magenta, ultra thin] (2-2.south east) -- (4-4.north west); } \end{pNiceMatrix}\qquad \begin{pNiceMatrix} 3 & & & \\ & 555 & & \\ & & \Ddots & \\ & & & 66666 \CodeAfter \tikz{ \draw[teal, ultra thin] (1-1.center) -- (4-4.center); \draw[magenta, ultra thin] (2-2.south east) -- (4-4.north west); } \end{pNiceMatrix} \] \[ \begin{pNiceMatrix} a & & & \\ & b & & \\ & & \ddots & \\ & & & d \CodeAfter \tikz{ \draw[teal, ultra thin] (1-1.center) -- (4-4.center); \draw[magenta, ultra thin] (2-2.south east) -- (4-4.north west); } \end{pNiceMatrix}\qquad \begin{pNiceMatrix} a & & & \\ & b & & \\ & & \Ddots & \\ & & & d \CodeAfter \tikz{ \draw[teal, ultra thin] (1-1.center) -- (4-4.center); \draw[magenta, ultra thin] (2-2.south east) -- (4-4.north west); } \end{pNiceMatrix} \] \[ \begin{pNiceMatrix} x & & & & \\ & x+y & & & \\ & & \ddots & & \\ & & & \sqrt{x-y} & \\ & & & & \dfrac{x}{y} \CodeAfter \tikz{ \draw[teal, ultra thin] (1-1.center) -- (4-4.center); \draw[magenta, ultra thin] (2-2.south east) -- (4-4.north west); } \end{pNiceMatrix}\qquad \begin{pNiceMatrix} x & & & & \\ & x+y & & & \\ & & \Ddots & & \\ & & & \sqrt{x-y} & \\ & & & & \dfrac{x}{y} \CodeAfter \tikz{ \draw[teal, ultra thin] (1-1.center) -- (4-4.center); \draw[magenta, ultra thin] (2-2.south east) -- (4-4.north west); } \end{pNiceMatrix} \] \end{document} With latin-modern-math: With kpfonts-otf:

I would like to add dimension arrows like the ones shown here. What is the most elegant way to do this in common? (Note that I am showing an example here; however, a good general method would be interesting.) So, for instance, the dimension arrows and labels should be placed evenly and systematically. Here is my own rather clumsy attempt: \documentclass[margin=5pt, tikz]{standalone} \usepackage{tikz} \usetikzlibrary{arrows.meta} \begin{document} %% Values \pgfmathsetmacro{\R}{2.0} \pgfmathsetmacro{\a}{1.9} \pgfmathsetmacro{\b}{sqrt(\R^2 - \a^2) + \R} \pgfmathsetmacro{\x}{\R+(sqrt(2)*sqrt(\R*(2*\R-\b)) +\b -2*\R)-\b} \begin{tikzpicture}[scale=1.5, font=\footnotesize, >={Triangle[length=0pt 2*4,width=0pt 4]}, ] %% Coordinates on the main segment \coordinate[label=below:$M$] (M) at (0,0); \coordinate[label=below:$O$] (O) at (-\R,0); \coordinate[label=below:$A$] (A) at (\R,0); \coordinate[label=below:$C$] (C) at (\R-\b,0); %% Draw main segment OA \draw[] (O) -- (A); %% Solution elements on the main segment \coordinate[label=below:$X$] (X) at (\x,0); % Dimension arrows \foreach \P in {C,M,X,A}{%% \path[draw=none, shorten <=1em] (\P) -- +(0,-1.125) coordinate[pos=0.3] (\P-1) coordinate[pos=0.6] (\P-2) coordinate[pos=0.8] (\P-3) coordinate[pos=1.0] (\P-4); }%% \draw[shorten <=1em] (X) -- (X-2); \draw[<->] (C-1) -- (X-1) node[midway, fill=black!1]{$r$}; \draw[shorten <=0.25em] (M-1) -- (M-2); \draw[<->] ([yshift=0.5em]M-2) -- ([yshift=0.5em]X-2) node[midway, below]{$x$}; \draw[shorten <=1em] (C) -- (C-4); \draw[shorten <=1em] (A) -- (A-4); \draw[<->] (C-3) -- (A-3) node[midway, fill=black!1]{$b$}; %% Draw points on the axis (solution) \foreach \P in {A, X} \draw[fill=black!1] (\P) circle (1.5pt); %% Draw points on the axis (task) \foreach \P in {C, M} \draw[fill=black!1] (\P) circle (1.5pt); \draw[fill=black!1] (O) circle (1.5pt); \end{tikzpicture} \end{document}

Just for fun, I try to mimic this question with tikz-extension with tabularray: \documentclass{article} \usepackage{tabularray} \UseTblrLibrary{tikz} \begin{document} \begin{tblr}{ colspec={*{3}{Q[c,m,12mm]}}, hlines,vlines, } multiple lines & b & c \\ d & multiple lines & f \\ g & h & i \\ \end{tblr} \bigskip \begin{tblr}{ colspec={*{3}{Q[c,m,12mm]}}, % hlines,vlines, rows={rowsep=+5pt}, columns={colsep=+5pt}, } multiple lines & b & c \\ d & multiple lines & f \\ g & h & i \begin{tblrtikzabove}% \foreach \i in {1,...,\arabic{rowcount}}{ \foreach \j in {1,...,\arabic{colcount}}{ \coordinate (A) at ([xshift=+2pt,yshift=-2pt]h\i-|v\j); \coordinate (B) at ([xshift=-2pt,yshift=+2pt]h\inteval{\i+1}-|v\inteval{\j+1}); \draw[cyan] (A) rectangle (B); } } \draw[magenta] ([xshift=-1.5pt,yshift=+1.5pt]h1-|v1) rectangle ([xshift=+1.5pt,yshift=-1.5pt]h\inteval{\arabic{rowcount}+1}-|v\inteval{\arabic{colcount}+1}); \end{tblrtikzabove}% \end{tblr} \end{document} However, the bounding box was not enlarged with the overlay. It looks not a good idea to do so with tabularray...? Now I turn to focus, if we need to draw something outside the tblr, how to enlarge the corresponding bounding box? Edit Now let's only focues the bounding box, similar to this post(?), following example: \documentclass{article} \usepackage{showframe} \setlength{\parindent}{0pt} \usepackage{tabularray} \UseTblrLibrary{tikz} \usetikzlibrary{bending} \begin{document} \begin{tblr}{colspec={*{3}{Q[c,m,12mm]}},hlines,vlines} multiple lines & b & c \\ d & multiple lines & f \\ g & h & i \begin{tblrtikzabove}% \draw[ultra thick,cyan,-latex] (1-1.north west) to[bend right] (3-1.south west); \end{tblrtikzabove}% \end{tblr} \bigskip some text% \begin{tblr}{colspec={*{3}{Q[c,m,12mm]}},hlines,vlines} multiple lines & b & c \\ d & multiple lines & f \\ g & h & i \begin{tblrtikzabove}% \draw[ultra thick,cyan,-latex] (1-1.north west) to[bend right] (3-1.south west); \end{tblrtikzabove}% \end{tblr} \end{document} The "some text" was overlapped with the arrow outside the tblr, my focus here, was how to enlarge the bounding box of tblr in similar case?

How can I obtain the hollowed-out sphere effect? The drawing above is my original done many years before. \documentclass{article} \usepackage{tikz} \usetikzlibrary{arrows.meta, calc, positioning, shapes.geometric} \begin{document} \begin{tikzpicture}[ scale=1.2, axis/.style={thick, ->} ] \coordinate (O) at (0, 0); \coordinate (X) at (-2, -2.3); \coordinate (Y) at (5.5, 0); \coordinate (Z) at (0, 4); \coordinate (P) at (3.1, 1.3); \draw[axis] (O) -- (X) node[left, font=\large, xshift=-3pt] {$x$}; \draw[axis] (O) -- (Y) node[below, font=\large, yshift=-3pt] {$y$}; \draw[axis] (O) -- (Z) node[left, font=\large, xshift=-3pt] {$z$}; \begin{scope} \shade[ball color=gray!30!white, opacity=0.85] (O) circle (0.9); \draw[gray!60, thin] (O) circle (0.9); \fill[gray!60!black, opacity=0.9] plot[smooth cycle, tension=0.7] coordinates { ($(O)+(-0.2, 0.4)$) ($(O)+(0.5, 0.5)$) ($(O)+(0.6, -0.4)$) ($(O)+(0.1, -0.6)$) ($(O)+(-0.3, -0.3)$) }; \shade[inner color=black!80, outer color=gray!70!black, opacity=0.5] plot[smooth cycle, tension=0.7] coordinates { ($(O)+(-0.2, 0.4)$) ($(O)+(0.5, 0.5)$) ($(O)+(0.6, -0.4)$) ($(O)+(0.1, -0.6)$) ($(O)+(-0.3, -0.3)$) }; \end{scope} \fill[black] (O) circle (0.07) node[below, yshift=-4pt, font=\large] {$O$}; \draw[->, >=Stealth, shorten >= 2.5pt, shorten <= 2pt] (O) -- (P) node[midway, above, yshift=2pt, font=\large] {$r$}; \fill[black] (P) circle (0.08) node[above, yshift=3pt, font=\large] {$P$}; \node[right, font=\Large\itshape, xshift=2pt, yshift=-2pt] at (P) {$m$}; \node[below, font=\large] at (0.2, -0.95) {$M$}; \end{tikzpicture} \end{document}

Here below is my original code: \documentclass[tikz,border=5pt]{standalone} \usepackage{fourier} \usetikzlibrary{bending,patterns.meta,angles,quotes} \begin{document} \begin{tikzpicture}[>=latex] \draw[thick,->] (0,0) -- (10,0) node[below] {$x$}; \draw[thick,->] (0,0) -- (0,-3) node[right] {$y$}; \draw[ultra thick] (7,2) -- (7,0) coordinate (A) -- (8,0) -- (8,-4) -- (7,-4) coordinate (B) -- (7,-6); %%%%%%%%%%%%%%%% path coordinate duplicated \fill[pattern={Lines[angle=-45,distance={5pt}]},preaction={fill=white}] (7,2) -- (7,0) -- (8,0) -- (8,-4) -- (7,-4) -- (7,-6) -- ++(.5,0) -- ++(0,+1.5) -- ++(1,0) -- ++(0,+5) -- ++(-1,0) -- ++(0,1.5) -- cycle; %%%%%%%%%%%%%%%% \draw(0,0) node[label={[label distance=-2.5mm]above left:$O$}] (O) {} -- (7,-4) pic[draw,<->,angle radius=2cm,angle eccentricity=1.15,"$\alpha$"] {angle = B--O--A}; \end{tikzpicture} \end{document} which gives: However, the path: (7,2) -- (7,0) -- (8,0) -- (8,-4) -- (7,-4) -- (7,-6) appeared twice, and I think that is duplicated.

I'm attempting to create a 3D plot of a connected sum of two tori in LyX using the tikz-3dplot package, aiming for a visual representation similar to the image linked here Link Here. I have seen similar plots online, generated by Alternative packages (most of the are similar to the picture in Wikipedia under "Connected Sum"), In which I have no interest.

I'm working with a blank Beamer presentation template and want to recreate a sidebar similar to one shown in the image below. Unlike typical Beamer sidebars that extend to the page's edge, this one is part of a custom frame. I'd like the sidebar to display boxed sections with sharp drop shadows. The current section should be highlighted by a red shadow, while the current subsection should be bolded and appear on a white horizontal strip. Subsections from other sections should remain hidden until the presentation reaches that specific section, at which point they should appear in a dropdown list in the sidebar (e.g. in the image, we're on SO so subsections of SO are shown in the sidebar, but subsections of Section Two and Section Three are not). Note: By 'subsection' I really mean slide titles. How can I implement this effect in LaTeX? Any help would be appreciated. \documentclass[11pt]{beamer} \usepackage{tikz} \usepackage{microtype} \usepackage{xcolor} \usepackage{soul} \usetikzlibrary{calc} \usepackage{ lmodern, babel, amsmath, eurosym } \definecolor{darkpastelgreen}{rgb}{0.01, 0.75, 0.24} \usepackage[default]{sourcesanspro} \usepackage[T1]{fontenc} \setbeamertemplate{navigation symbols}{} \setbeamertemplate{background}{% \begin{tikzpicture}[overlay,remember picture] \fill[sharp corners,fill=darkpastelgreen] ($ (current page.north west) + (0.4cm,-0.4cm) $) rectangle ($ (current page.south east) + (-0.4cm,0.4cm) $); \end{tikzpicture}% \begin{tikzpicture}[overlay,remember picture] \fill[sharp corners,color=white] ($ (current page.north west) + (0.5cm,-0.5cm) $) rectangle ($ (current page.south east) + (-2cm,0.5cm) $); \end{tikzpicture}% } \setbeamersize{text margin left=0.8cm, text margin right=0.85cm} % Reduce side margins \setbeamertemplate{frametitle}{\color{black}\bfseries\insertframetitle \nointerlineskip \bigskip } \addtobeamertemplate{frametitle}{\vspace*{0cm}}{\vspace*{-0.4cm}} \addtolength{\headsep}{0.6cm} \begin{document} \begin{frame}[t]{} \frametitle{A Subsection} Slide content goes here... \end{frame} \end{document}

Cross-posting from Stack Overflow: https://stackoverflow.com/q/78347764/2777074 Good people! I'm trying to draw some shapes with an angular colour gradient, but I am unable to find the general syntax for how fill a shape like that. I'm going to need to draw an awful lot of these diagrams, but to give you an idea of the basic way I want these things to look like when they're finished, I am attaching this picture: So, what I want is something so that I can specify "the gradient starts with colour X at angle A, and ends with colour Y at angle B". Does TikZ picture have such a function, or is it necessary to define something on one's own? Look forward to your responses! The only thing I've been able to come up with would be to use the method described in this answer to create a circular shape as a background, then to "hide" most of it with white with a cut-out of my shape remaining, but the problem with this approach is not only that it's kind of inelegant, it also will not work if I need to have several shapes next to one another. https://stackoverflow.com/questions/72813749/tikz-fill-a-circle-with-shading-color-by-angle EDIT: It being requested that I add some code snippet, I have put together this one, which produces the figure I have in mind, albeit without the desired gradient: \begin{tikzpicture} \draw[thick, arrows=<->] (-5,0)--(5,0); \draw[thick, arrows=<->] (0,-5)--(0,5); \draw[fill=red, draw=none] (2.5,0) arc (0:225:2.5) -- (225:2.2) -- (243:3) -- (225:3.8)--(225:3.5) arc (225:0:3.5) -- cycle; \draw[fill=blue, draw=none] (290:2.5) arc (290:335:2.5) -- (335:2.2) -- (353:3) -- (335:3.8) -- (335:3.5) arc (335:290:3.5) -- cycle; \end{tikzpicture} The image produced looks as follows:

I am currently facing a challenge in LyX where, after typing several lines of text, I insert TikZ code either inside a TeX box or directly into the apex preamble. However, I have observed that the text following the TikZ code is not visible. In the case of placing the code in the preamble, none of the text I have written in the document is visible. I am seeking assistance in resolving this issue and understanding how to ensure the proper display of text below inserted TikZ code in LyX. Any guidance or solutions would be greatly appreciated.

I want to get this kind of figures in LaTeX: I am pretty sure these were not written manually in tikz, since it would take too much time. How can I draw hard geometry in tikz without needing to spend half an hour on each figure? I tried geogebra but the figures produced are horrible. Even by changing the software’s settings you still get ugly tikz figures and the nodes labels are placed incorrectly. Please help me, maybe with something like a WYSIWYG program for tikz, because it is not the best option to manually write the tikz code for 200 figures..

I would like to represent the densest sphere packing in dimension 3 as the following picture, for a beamer presentation. Is Tikz the way to go for it? It is not a real 3D drawing since I only want a fixed representation of the picture, right? Thank you for your help.

The style of plots, as shown in the example of a thesis I saw, can be found in literature of topics ranging from mechanical engineering to physics. I am primarily interested to know if this is a specific style option or package (like using colorbrewer sets for colours). (If it is none of this, I will try to re-imagine it myself.) So far, I have checked the TikZ Galery for any other examples of this and looked through math sans serif fonts, but it was not successful yet. Just as an addition, the reason I am searching for a package or something similar, is that this style of diagram is fairly widespread. And not only do the axes look differently than regular pgfplots (see the dimensions for the percentage on the y-axis), there's also the different fontand the arrows in the axis description. These characteristics are always the same when these diagrams can be found in books which makes me think that this is a fundamental design.

Question How to draw the letter π not in the standard way (i.e. \pi)? I mean "draw", not "type"! Today there will be no \pi, but there will be something like this \documentclass[tikz]{standalone} \begin{document} \begin{tikzpicture} \draw (0,2)--(3,2); \draw (1,0)--(1,2); \draw (2,0)--(2,2); \end{tikzpicture} \end{document} (inspired by David Carlisle – I draw this in TikZ just because I don't know how to use picture ;)) Or this \documentclass[tikz]{standalone} \usepackage{tikzducks} \begin{document} \begin{tikzpicture} \duck \duck[xshift=1cm,yshift=2cm] \duck[xshift=1cm,yshift=4cm] \duck[xshift=1cm,yshift=6cm] \duck[xshift=0cm,yshift=8cm] \duck[xshift=-2cm,yshift=7.5cm] \duck[xshift=2cm,yshift=8cm] \duck[xshift=4cm,yshift=8cm] \duck[xshift=6cm,yshift=8cm] \duck[xshift=8cm,yshift=8cm] \duck[xshift=5cm,yshift=6cm] \duck[xshift=5cm,yshift=4cm] \duck[xshift=5.5cm,yshift=2cm] \duck[xshift=6.5cm,yshift=0cm] \duck[xshift=8cm,yshift=1cm] \node[font=\huge] at (4,11) {Happy $\pi$ day with \verb|tikzducks|!}; \end{tikzpicture} \end{document} They are my proudest π drawings, and as today is Pi day, I'd like to see yours! Well, why didn't I delay the time of asking the question by 8 minutes? I asked this at 1:51:31 UTC time, and the "Pi second" of this year is at 1:59:26 today!

I would like to create the following image in tikz. I am completely new to it, so I tried to change the code at http://www.texample.net/tikz/examples/free-body-diagrams/ to \def\iangle{90} \def\down{-90} \def\arcr{0.5cm} \begin{tikzpicture}[ force/.style={>=latex,draw=blue,fill=blue}, axis/.style={densely dashed,gray,font=\small}, M/.style={rectangle,draw,fill=lightgray,minimum size=0.5cm,thin}, m/.style={rectangle,draw=black,fill=lightgray,minimum size=0.3cm,thin}, plane/.style={draw=black,fill=blue!10}, string/.style={draw=red, thick}, pulley/.style={thick}, ] \matrix[column sep=1cm] { \draw[plane] (0,-1) coordinate (base) -- coordinate[pos=0.5] (mid) ++(\iangle:3) coordinate (top) |- (base) -- cycle; \path (mid) node[M,rotate=\iangle,yshift=0.5cm] (M) {}; & %%% % Free body diagram of M2 pulley \draw[pulley] (top) -- ++(\iangle:0.25) circle (0.5cm) ++ (90-\iangle:0.5) coordinate (pulley); \draw[string] (M.east) -- ++(\iangle:2.0cm) arc (90+\iangle:0:0.25) -- ++(0,-1) node[m] {}; \\ }; \end{tikzpicture} but I am not close. Some basic pointers would be appreciated.

How can I create a graph of the forces acting on an object like the one in the picture? \documentclass{article} \usepackage{tikz} \begin{document} \begin{tikzpicture} \end{tikzpicture} \end{document}

I have a cuboid made from unit squares which in 2D looks like the following: Considering a 3D version of this (i.e. a cuboid). I wanted to use Tikz to demonstrate some of the possible deformations that we can introduce to this 3D grid. I wanted to show arbitrary streching (in any direction), shearing (where one half is pulled in one direction and the other half is pulled in the other direction) and some general inhomogeneous deformation (a deformation which cannot be described by any of rotations, shearing, streching etc. It is a very general transformation). I would like each of the spheres shaded and shown in different colours for the different transformations. Many thanks for your help in advance!!!!

I'm styling my beamer presentation using PGF picture and I want to add a textbox with a specific width. The following line doesn't provide a width parameter. \pgftext[at=\pgfpoint{.05\paperwidth}{-.3\paperheight},left,base]{\inserttitle} Note: I strictly want to use PGF. Tikz is not an option.

I am trying to create a table with alternating row colours and rounded corners. I combined two answers so far to achieve this: Thorsten Donnig's answer about alternating row colours. Jake's answer about adding rounded corners to a table. This works great in general, but the problem is that the alternating row colours method fills a proper square, not a rounded one, and the row colour "leaks" outside the table border. See the top left and bottom left corners of the image below. Is there an easy way to fix this? Maybe by using the named tikz node to clip everything outside it? Issue: MWE: \documentclass[border=10pt,10pt,table]{standalone} \usepackage{tikz} \usepackage{xcolor} \usepackage{array} \usepackage{booktabs} \usepackage{tabularx} \definecolor{tablerow1}{RGB}{225,217,205} \definecolor{tablerow2}{RGB}{236,229,221} \begin{document} \rowcolors{2}{tablerow1}{tablerow2} \begin{tikzpicture} \node (thetable) [inner sep=0pt] { \begin{tabularx}{\textwidth}{>{\raggedright\arraybackslash\hsize=1.4\hsize}X>{\raggedright\arraybackslash\hsize=0.6\hsize}X} \arrayrulecolor{white} \textbf{Column 1} & \textbf{Column 2} \\ \hline Some text. & Some text. \\ \hline Some text. & Some text. \end{tabularx} }; \draw [rounded corners=.5em] (thetable.north west) rectangle (thetable.south east); \end{tikzpicture} \end{document}

I would like to typeset the top part of Pascal's triangle. To get the triangle with the names of the binomial coefficients, i.e., {n \choose k}, I used the following code \begin{tikzpicture} \foreach \n in {0,...,4} { \foreach \k in {0,...,\n} { \node at (\k-\n/2,-\n) {${\n \choose \k}$}; } } \end{tikzpicture} The result is this Now I want to be equally lazy and do something like this for the values of the binomial coefficients, i.e., replace {\n \choose \k} in the node label with \CalculateBinomialCoefficient{\n}{\k} where \CalculateBinomialCoefficient is a hypothetical macro that calculates the binomial coefficient. Has anyone done something like that? The result should look like this:
