Nothing built in at the moment, no.  You could rebroadcast the paths as LINE_STRIP markers.<div><br></div><div>Josh<br><br><div class="gmail_quote">On Fri, Sep 10, 2010 at 6:17 AM, Daniel Maier <span dir="ltr">&lt;<a href="mailto:maierd@informatik.uni-freiburg.de">maierd@informatik.uni-freiburg.de</a>&gt;</span> wrote:<br>

Hi!<br>
<br>
Is there some way to render paths wider in rviz?<br>
You can easily change the color but not the width of the trajectory<br>
which would make it better recognizable.<br>
<br>
Thanks<br>
Dan<br>
