I have never come across this limitation, although metapost usually logs
messages of seeming complaint. I inquired on the forum years ago, and one
of the Martin's or Stacho assured me that it should never actually run out.
Not sure if I have ever plotted 66km of centreline? I have probably come close.<u></u><u></u></span></font></b></p><span class="">
