The line-bodies keep going through each other instead of tightening around each other. I used line bodies so I could apply cable sections to them (so that they experience zero force in compression.) However, it appears that my ability to apply connections\/contacts to line bodies is very limited when I use line bodies. I tried writing a keyword script (below) but I&#8217;m having trouble getting the syntax right. I tried adding mesh elements to two named set of parts (the top string and the bottom string) and assigning those names to ssid and msid &#8212; but no luck.
