This question already has an answer here:

I want to draw block diagram of a system. I used \framebox command to create blocks. But when I write long text inside the box it comes out of the boundaries of block. How can I write text in multiple lines? I used following code for making block diagram

\setlength{\unitlength}{0.14in} % selecting unit length
\centering % used for centering Figure
\begin{picture}(32,15) % picture environment with the size (dimensions)
% 32 length units wide, and 15 units high.
\put(3,4){\framebox(6,3){Symbol Mapping}}
\put(-1,6.5) {$u(k)$}\put(30,6.5) {$y(k)$} \put(9.5,6.5)
{$x_{B}(k)$}\put(19.5,6.5) {$x_{C}(k)$}
\caption{An LNL Block Oriented Model Structure} % title of the Figure
\label{fig:lnlblock} % label to refer figure in text

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • \begin{figure*}[h] you can not use h with figure* so this figure is not allowed anywhere and will go to the end of doument unless flushed with \clearpage – David Carlisle May 24 '15 at 10:02
  • \framebox(..){\parbox{5cm}{long text here....}} will allow multi-line text – David Carlisle May 24 '15 at 10:04
