Greetings -

Need to create a mirror image of an exhaust system.  Having trouble.  Plan was to create a mirror feature of the original part features, then extrude-cut to eliminate the original features.

I have successfully created the mirror image - "Mirror1" exists in the FeatureManager design tree - but I can't see it on the part.  It doesn't apear to be suppressed or hidden, but it's just...not there.

Toss me a clue?  File is attached.

Thanks...
