I have a feature, say an extrusion that I am patterning, a circular pattern for example. After I'm done, I have two of the extrusions but the second one is not a feature by itself, it is a pattern, its feature is the circular pattern, which includes the original. So now I want to mirror this result  Of course when I mirror, it tries to mirror the original as well. How do I solve this? I assume I somehow have to convert this second extrusion into a feature in its own right

Thanks guys.
