square hole and round hole coincident

Yes....either a centerline in the square hole...could be between two planes as well as points, mated to surface of shaft....or.... sketch with circle in/on square hole...or if they have same dimension two tangent mates.

I always put an axis down the middle of square holes for this purpose.

You might also try using a Symmetry mate, mating the round hole's axis to the sides of the square hole. You would need to do this twice, once for each pair of opposing faces on the square hole.

Sorry....meant axis...not centerline

There's also the width mate, new in 2007.

Constrution line in the diagonal, centerpoint on it.

Mate the point concentric

Where is the axis line and the centerline different? If I put in a center line, is that not the axis line? Where is the insert axis command? Sorry I am not as experienced. Thanks

Well....it's just a SW terminology I guess..... a centerline is something I draw in a sketch or insert in a drawing... an axis is a feature I insert in a part or an assembly,but in reality it's kinda the same thing. You find the axis insert command under Insert / Reference Geometry.
