First sorry for my english.
I have problem about activate symmetry.
It’s little off from object.
I turn on X and Z.
It’s X is works ok, but Z doesn’t.
So how to fixed it ?
Please help somebody!!!
I encountered this problem earlier. It is fairly easy to fix. The model is slightly off the z axis. Turn on axis or plane view and use the move tool [The one at the top of Zbrush not on the side] to center it on the z axis.
I hope this helps. 
Transform:setpvt Transform:clrpvt and the move mode answered above.
