# problem with multicol and big picture

The picture is too high to stay in the first column, but the remaining text spreads over the entire height of this column. The only way I've found to avoid this problem is to place an empty vbox at a certain height. This is hardly satisfactory. What's the best method?

\documentclass{scrartcl}
\usepackage{tikz}
\usepackage{multicol,lipsum}
\setlength{\columnsep}{24pt}
\setlength{\columnseprule}{0.4pt}

\begin{document}
\begin{multicols*}{2}

\section{Contruction with inversion}

Let us consider the circle $\mathcal{T}$ of center $T$ point common to the circles $\mathcal{A}$ and $\mathcal{B}$ and tangent to the line $(EF)$. It intercepts the two circles at 4 points which define two lines $\mathcal{L_A}$ and $\mathcal{L_B}$ perpendicular to the line $(AB)$.

Consider the inversion of center $T$ with respect to the circle $\mathcal{T}$. The circles $\mathcal{A}$ and $\mathcal{B}$ have as inverses the lines $\mathcal{L_A}$ and $\mathcal{L_B}$.

The orange circle passing through $T$ and tangent to the circle $\mathcal{T}$ and to the line $(EF)$ is therefore tangent to the line $(EF)$. This circle is therefore tangent to the lines $\mathcal{L_A}$ and $\mathcal{L_B}$ since $(EF)$ is tangent to the circles $\mathcal{A}$ and $\mathcal{B}$.

• What the results tell, is that you need more text on the first column, moving \lipsum[2] before the picture will produce better results. The figure will then move into a more natural position. Commented Jan 15 at 2:07
• If so then manual intervention, like you did with the vbox or a vspace* is the best. I have many similar examples in one of my documents. In the end I moved away from multicols for many of them and used two minipages (with a lot of manual adjustments) to get nice arrangements. I can also arrange different width columns this way.

• Try this \def\vstretch#1{\vspace{\stretch{#1}}}  and then \vstretch{1}\null just where you have the vbox. Commented Jan 15 at 9:52
• @yannisl yes this could be a solution. You can turn this comment into an answer !! Commented Jan 15 at 10:59

This adds enough text to fill the first column, then uses my linked solution.

If you like big gaps, you can use

\split{\vfill}{\noindent\begin{tikzpicture}
\draw (0,0)--(\columnwidth,15) (0,15)--(\columnwidth,0);
\end{tikzpicture}}
