Hello Francois,

we use a user defined rope line. Here is the metapost code snippet:

# FUND line rope u:rope -------------------------------#

def l_u_rope (expr P) =

T:=identity;

pickup pensquare scaled (1.0*u/10);

thdraw P withcolor (0.35,0.75,1.0);

pickup PenC;

thdraw P dashed dashpattern(on 1bp off 2bp on 1bp off 2bp);

enddef;

It is a dashed white/blue line and looks like a static rope.

Best regards

Christian
