Is there a way to quickly replace left half of my sculpt with mirror image of right half? My sculpt model has become a little unsymmetrical and I'd like to replace the left half with a mirror image of the right.  I know there's an option for this under Dyntopo, but that leaves artifacts.  My center line is still in tact - is there something that will simply delete the left half of my model and replace it with the right?
You can try going into edit mode, then under mesh options, symmetrize. On the popup option choose direction of the symmetry (ie. -x to x)
