Umm... you REALLY should use a better string element than mine! It is really not
very accurate as it doesn't model the three strands at all. It was just a quick
hack, and it has fixed colors, if LEGO ever do red or white string it won't
work.

As for naming? arc_string1 and spline_string1? Maybe I'm not understanding the
question... (the 1 is to allow for future improved versions...)

| (...) Will it be a problem if LEGO ever do green string? ;) At this time, using the best available string element seems like the way to go. AFAIK, Larry's string is the best. Steve (20 years ago, 26-Apr-05, to lugnet.cad)
