TikZ Application [duplicate]

This question already has an answer here:

I am trying to learn drawing in latex with TikZ for simple shapes. But when I want to draw shapes in 3D or special shapes I am confused. I think there are some applications to make it easier and convert an image to latex code. Can you give me suggest for the application?

• Does the linked question cover what you are asking or is there something more specific you need to tackle? – Andrew Swann May 3 '17 at 16:01

I would recommend using TikZ directly. It's not that difficult.

The TikZ documentation contains some very good introductions in the first chapter for different applications. After reading the first ("Tutorial: A Picture for Karl’s Students" pages 29--46) you should know the basics and a little more.

TikZ supports specifying 3D coordinates, as described in chapter 13 "Specifying Coordinates" on pages 131, 132. By default the x-axis points right, the y-axis upwards and the z-axis out of the screen. In the following example I have changed this so that the x-axis points out of the screen, the y-axis to the right and the z-axis upwards:

\documentclass[tikz]{standalone}

\tikzset{
3D/.style={
x={(-3.85mm, -3.85mm)},
y={(1cm, 0cm)},
z={(0cm, 1cm)},
},
}

\begin{document}
\begin{tikzpicture}[3D]
\draw[->] (0,0,0) -- (2,0,0) node[right] {$x$};
\draw[->] (0,0,0) -- (0,2,0) node[below left] {$y$};
\draw[->] (0,0,0) -- (0,0,2) node[below right] {$z$};
\end{tikzpicture}
\end{document}
