Dear list,

\documentclass{article}
\usepackage{esvect}
\parindent=0pt
\begin{document}
\begin{pspicture}(-0.5,-0.5)(6,3)%\psgrid
\psset{arrowscale=1.5}
\cnode(0,0){0cm}{O}
\cnode(4,0){0cm}{A}
\cnode(6,2){0cm}{B}
\cnode(2,2){0cm}{C}
\ncline{->}{O}{B}
\nbput[nrot=:U]{$\vv{b}+\vv{a}$}
\naput[nrot=:U]{$\vv{a}+\vv{b}$}
\ncline{->}{O}{A}
\nbput{$\vv{b}$}
\ncline{->}{O}{C}
\naput{$\vv{a}$}
\ncline{->}{A}{B}
\nbput{$\vv{a}$}
\ncline{->}{C}{B}
\naput{$\vv{b}$}
\end{pspicture}
\end{document}

Now as you see, three arrows end in the node B. That doesn't look too
amazing, although it is correct. I need to blow up the arrowsize, due
the document will be scaled down for print. When not blowing up the
arrowsize, the result looks better, but the arrows are almost not seen
in the scaled down document.

Now how to make that look more aesthetic? Are there any conventions how
to handle such a case? For sure i could give a little nodesep to the
arrow lines, however then they do not really end in the node B...

Thanks for any hints!

Regards,

Juergen
