..yes,.. although it seems like it could work, I personally would not assume the parent/child relations or the reference geometry would resolve this.. it is just (user experience) on the historical fringe/limits of who, where and what?
And.. it becomes a, "why" would I do this now in history?.. ..that is,.. it would be better to role back the feature to be used in a linear order with fewer assumptions.
File?
If you can attach your file, we can take a look.
I don't know why the feature is showing in your tree, but I believe the feature didn't work because it can't use the same surfaces for the mirror as the original. As Dario Karalic suggested above, creating half of the model and then modeling the body would probably be your best option, but another option would be:
Why am I having problems with the Pattern (or Mirror) feature in my Part? may be of more help if you'd like to take a look.
Why isn't this mirror feature working as expected?
I had a similar issue. The Solidworks "mirror" command is not very well executed, IMO.
You don't need to change anything. In yours cases (symmetrical part) when creating a mirror, use "Body" as an object to be mirrored.
I agree. But Solidworks should be smart enough to realize if you are performing a mirror the face you are extruding "Up to" will be likely be in the opposite direction. The "dumb" preview gets it right.
IMO, the definition of a mirror is pretty simple. Mirroring a body/face/feature/sketch shouldn't care how the object to be mirrored was created. You have geometry X and mirror plane Y. Any other information is extraneous and can only lead to an improper solution.
The problem is you are not mirroring the object. Operation works fine when you select "Body". You do mirror for feature, so SW made offset mirror and ... extrude sketch to the indicated face. How is the program to know which face use for mirror? Parts are not always symmetrical. However, the fact is that the preview shows as we expected. But the preview is the job of the graphics card and we often see in preview the features but the SW refuses to perform the operation.

The program doesn't need to know which face to use to mirror. Don't worry about how that face was created. The face already exists. Mirror it.

Yes! You have right! Face exist and SW use it! Because you mirrored feature. In this feature end condition is described and SW make extrude to this face.
Scott. maybe this will convince you: Your case but with small modification. Now, say me haw you want use mirror extrude with face as end condition? As I wrote before: parts not always are symmetrical
If the "mirrored" feature and the parent feature aren't symmetric about the mirror plane, then the operation being performed isn't a mirror.
The same model. Only I used other metod for Extrude Boss and... mirror work even though the part is not symmetrical!
Because solid works does not know where "up to surface" is on the other side of the part.
I would model half of this part and then use mirror bodies (if part is symmetric) because it is much better and stable then mirroring features.
