Relative Positioning of parts in assembly

Probably a rather basic question but something I've been struggling to do for a while.


I have several "floating" parts that do not have any real relation to the other parts in the assembly except they are connected in some way. That is, they do have a reduced number of degree's of freedom but are not fully defined because of their nature.


A simple example is a series of buttons on a panel that connect o a circuit board. They do not have to be fully defined to serve their purpose but I would like to at least position them in an orderly way.


I can sort of do this by using distance mates but the problem is I can never made the center of the part's to each other which makes distance calculation somewhat tedious.


What I'm wanting to do is simply get the center of the parts(I can easily create the point of reference I'm after in a sketch or as an axis to a cylinder) and mate them. Maybe this is not the proper way to go about it?


Basically I simply want to specify only the relative distances between the centers of all the buttons I have and probably position the group(s) relative to the main assembly or leave it free floating.


Hopefully the question makes sense.
