How do I measure absolute 3d coordinates in IronCAD?

I have a model a past intern made in IronCAD a few years ago. Think of a paper towel tube with about 20 Cheerios randomly glued to the outside surface, and you'll have a pretty fair idea of what this model looks like. In this case the "Cheerios" are actually stubby thick-walled cylinders with a slot cut out of one side so the end-on view of these are more of a "C" than an "O". I am trying to get the 3D coordinates of the centers for each of the circles defined by either the ID or OD of these cylinders at the outermost edge.

Is there a straight-forward tool or method to do this? I could not find anything in the help pages or on the tool bars that looked promising. I don't care if it is just a window and I have to transcribe the values by hand.

Thanks.
