I want to patern an axis. I have a square hole and placed an axis at the center. I patterned the hole. The thing is I want to be able to patern the axis with it as a reference to the center of the hole for mating. Anyone have any ideas on referencing the center of these other square holes without creating 2 planes and an axis for each.

you could use a pattern sketch (circular sketch step & repeat)
Well, here's my idea for a workaround. Create an L-shaped extruded surface with its corner in line with the axis you want patterned. Pattern the surface body (you may have to select from the surface bodies folder). YOu should be able to use the edge of the patterned surfaces as a substitute in downstream features. You'll also have 2 planar faces you can use. The surfaces won't mess up your mass properties, and (IIRC) they won't show in drawing views. You can hide the surface bodies anyway.
If you're going to mate the same part into each of these holes, you could use a feature driven component pattern instead.

you're not gonna put a round peg in that square hole, are ya? ;o)
is there a reason why you don't use a component pattern so you don't have to mate the parts individually?
...or pattern a dummy extruded circular surface ... except that you can't pattern surfaces with other features (surfaces are considered "bodies" rather than "features"), ...plus extruded surfaces make a temp axis, but patterned surfaces don't... hmm, ok, so make a sketch pattern and extrude the circles to make temp axes... crap, it only puts a temp axis on the surface created by the first circle drawn, ...ok, pattern a separate dummy cylindrical solid body... again, you can't pattern bodies with features... ok, make 2 separate patterns, one for the feature and one for the dummy cylindrical solid body. That'll give you temp axes, but its a pretty ugly way to do it.
I give. I can't think of a good way to do that.
Since my previous post apparently didn't get through, I'll expand from here.
Extrude a L-shaped sketch instead of a circle. You can use the right-angle edge as an axis, and you'll even have a couple planar faces you might use later.
I made a sketch with 3 circles constrained to the centers and extruded it as surfaces this works although if you hide the bodies you also hide the centerlines. So I had to make them 100% transparent.
Thanks all for the ideas. I only wish there was a clean way.
