Hi everyone

Q1)I have two roundabouts at the same location. but the elevation of roundabouts is different. one of the roundheads is located on the ground (z=0) another one in 30 m under this one (z= -30). how can I evaluate each one separately? ( note: when I draw node it evaluates both of them at the same time)

Q2) part of my simulation, the tunnel passes under intersection when I evaluate node of intersection the cars pass tunnel also included in the result. Is there any way to excluded tunnel result from evaluation.
