This is a face I am working on, I want to mirror the left side that is already completed (and has more definition) to the right side

I went to the lowest level
hid the right half of the face

then when only the left side was visible I went to the highest level and masked it
I then unhid the right half, and then hit resym, and then smart resym


I tried to resym it level by level, starting at the lowest level and as you can see random lines and problems occurred
what am I doing wrong?:rolleyes:
