That’s right, you cannot show a distance line between centroid objects.
If you want to do that, you have to use a different method to put a fake atom at each centroid, and then measure the distance between the two fake atoms.
The other method is described in this previous post:
You would probably want to delete the centroid objects first, or just start over without centroid objects, so they won’t get in the way.
I hope this helps,

In the control panel distance c1 c2 gives me the distance as expected. However, I have not manage to generate a distance line by using the Structure Measurements/Distance tool. I think, it’s because it does not recognise the centroids as atoms. I’m attaching a snapshot of this just in case it helps.
