You have an option (somewhere in Attribute Editor, I can't remember where exactly) to display the object's pivot as a point helper...so you then just have to snap the first object's pivot to the point helper using V (vertex snap).
Suppose you have a cylinder and it's positioned anywhere in world space, as when you model and place something. You have a piece of geometry you want to, duplicate around this cylinder; although not just duplicate, but where the duplicate pieces are even as so when you duplicate it is a seamless piece, minus the merge vertices ?
Why I mentioned, in order for this to work I assume the piece needs to duplicate around the pivot of the cylinder but unless I'm approaching this wrong, maybe some sort of shrink mapping had to come into play although, not so that it's literally shrink mapping the geometry piece but so that it follows the contours or normals of the cylinder.
antweiler said, you have to make the pivot visible first, then while holding D and V on your keyboard, drag the pivot to the target pivot, use the wireframe mode to see where the pivots are.

My goal is to duplicate the plane around the cylinder, evenly.
The plane was a cylinder with 20 sides, so duplicating the plane around the cylinder should work flawlessly with the duplicate keyboard short-cut; this may be relatively easy and I'm missing something
I originally centered the pivot on the cylinder, then tried to have both pivots selected so I could snap the plane pivot to the cylinder pivot that didn't go as planned so I matched it the best I could. There is a mesh object attached to this mesh for manipulating.
Looking at the example in the .obj it seems like you can just select the cylinder faces, extract them (leaving the original geometry intact and creating a new object) and then push the polygon normal outward.
Kodde - I did try the duplicate options. Sonic Blue - That is what was originally done to the mesh.
Using the duplicate options, take the plane, and duplicate it around the cylinder, as I mentioned, it should duplicate successfully, roughly four times. The problem is not the duplication, rather look at the alignment of each of the duplication's, they are not aligned, perfectly.
Well I took a look at the obj, this issue is that the underlying cylinder, is not a proper cylinder, every edge has a different length, so you can't really expect to radially duplicate faces extracted from it and have them line up.

I know, that is the problem; there must a method !

You can snap to visible pivots.
To display pivots: Display-> transform Display ->Rotate Pivots to toggle on and off the pivot of selected objects.
Or in the Attr Editor of the transform node under Pivots->Display Rotate Pivot

Like this?
If not, could you post some practical examples, or a mockup of the desired result?

Try converting the edges of the top part of the cylinder to a spline, and then duplicate the plane along this newly created spline, this should work.
or select object a, select object b: modify > match transformations > match pivots. a´s pivot is now matched with b´s.
