Symmerty is not working properly with z modeler

[Dark_Angel]

Hello everyone i wanted to ask a question
i am using zbrush 4r7 and my zmodular is not working while trying to use symmetry along vertical axis because of some known reason my my vertices are not coming symmetrical with respect to the vertical axis thats why zmodular does not pic vertices of both sides at the same time because of dislocation of vertices from their expected position.

i want to ask why my vertices are not coming symmetrical with respect to the vertical axis although while using zsphere i was using symmetry for modeling my character.

see attached photo for more detail…
kindly reply as soon as possible. i would really appreciate any help

Sometimes Zsphere adaptive skins can turn out that way because the original Zspheres are twisted or rotated slightly. The easiest way to make your model symmetrical would be to use the Mirror and Weld function in the Modify Topology section of the Geometry sub palette. You can also go back and try to workout the problem with your original Zsphere rig, but be prepared to be very patient with the process.
