[Chimera-users] measuring distance between an atom and centroid of an aromatic ring

Hello Chimera Users,

I need to measure and mark the distances of a few atoms to the center of an
aromatic ring.

I could define and create a centroid and plane for the ring. However, I am
unable to measure or mark the distances of the surrounding atoms from the
centroid of the ring (This is an exercise to show the ring current effect
of the aromatic ring on the chemical shifts of the neighboring protons).

Could anyone please give a hint on how I can go about this?

thanking you in advance,
best wishes,
