How can I delete this external reference (mirrored part using plane of another part)

I have a reference that I want to delete. I did a "Mirror Part" inside
of an assy, and used a plane/face of a part inside that assy to mirror.
I didnt relize I did that the mirrored part is referencing that assy
until a mth or so later.

When I do a "List External References", the part that the referenced
plane is shown.

When I do a "Find References", the assy the plane is referenced in is
shown

How can I get rid of/delete this reference?

 

When you list your external references, you get two buttons below the
listing, "Break All" and "Lock All". As the "All" implies, they will lock or
break ALL of the external references. That's probably not what you want to
do.

It seems like you should be able to edit the "Mirror Part" and reference a
plane that is not in of another part. That seems like a much better
approach, provided you can do it.

Create a plane in the part that is in the same position as the
externally referenced plane, then edit your features so that they
reference the plane that's in your part.

If the plane is at an odd position, it may be necessary to use a 3D
sketch to pin down the plane position. For this, I prefer to use two
sketched lines in a 3D sketch. Sketch the lines coincident to the
external plane, then remove all references and constrain the lines with
no external references(a couple simple "fix" constraints will put you
in business).

Beware that if you are changing the plane that a sketch is on, you may
be in for some surprises if your planes are in opposite directions (try
really hard to avoid this), or if the horizontal references are not the
same. You may need to edit sketches accordingly.
