# Parallel Lines between Two Blocks (Latex)

• LaTeX
Hello all,

I have two blocks, and I want to draw multiple parallel lines between them. This is the Latex code I have

Code:
\documentclass{article}

\usepackage{tikz}

\usepackage{amsmath,bm,times}

\begin{document}
\pagestyle{empty}

\tikzstyle{sensor}=[draw, fill=blue!20, text width=5em,
text centered, minimum height=2.5em]
\tikzstyle{naveqs} = [sensor, text width=4em, fill=gray!40,

\begin{tikzpicture}
\node (naveq) [naveqs, name=S2P] {S/P};
\node (naveq) [naveqs, name=FFT, right of=S2P,node distance=3cm] {FFT};

\end{tikzpicture}

\end{document}

What is the best way to do so?
