Use positioning can control the individual vertical position of nodes. But is there any way to control the default vertical spacing?
\documentclass{article}\usepackage[utf8]{inputenc}\usepackage{tikz}\usetikzlibrary{shapes,arrows,positioning}\begin{document}\pagestyle{empty}\tikzstyle{decision} = [diamond, draw, text width=4.5em, text badly centered, node distance=3.5cm, inner sep=0pt]\tikzstyle{block} = [rectangle, draw, text width=6em, text centered, rounded corners, minimum height=4em, node distance=3.5cm,minimum height=2em]\tikzstyle{cloud} = [draw, ellipse, node distance=3.5cm, minimum height=2em]\tikzstyle{line} = [draw, -latex']\begin{tikzpicture}[node distance = 1cm, auto] \node [block] (1st) {1st}; \node [block, right of=1st] (2nd1) {2nd1}; \node [block, above=0.7cm of 2nd1] (2nd2) {2nd2}; \node [block, below of=2nd1] (2nd3) {2nd3}; \node [block, right of=2nd1] (3rd1) {3rd1}; \node [block, above of=3rd1] (3rd2) {3rd2}; \node [block, above of=3rd2] (3rd3) {3rd3}; \node [block, below of=3rd1] (3rd4) {3rd4}; \node [block, below of=3rd4] (3rd5) {3rd5}; \path [line] (1st) -- (2nd1); \path [line] (2nd1) -- (2nd2); \path [line] (2nd1) -- (2nd3); \path [line] (2nd2) -- (3rd3); \path [line] (2nd1) -- (3rd1); \path [line] (1st) -- (2nd1);\end{tikzpicture}\end{document}Like this. I changed the vertical position of 2nd2 but others remains. Do I have to add individual vertical spacing control of every nodes?
