Is the sketch marked adaptive?
Is the sketch shared?
If the mirror was done post-sharing, the extrusion command will only "see"
the profile if the original feature (pre-share) is marked un-adaptive.

> I don't understand this but when I do a mirror in a sketch and try to
extrude a cut into a part Inventor views the mirrored portion as an unclosed
profile. Is there a way to force the mirrored portion to become a closed
profile without removing the mirror constraint? And yes the part is semetric
in all axis.
