Having trouble getting the symmetry feature to work in the Vertex Modeler.  I make a selection of a few faces, click Symmetry and when I move the faces, nothing happens.  The green divider box moves, but the action doesn't mirror on the other side of the model.  What am I doing wrong?

 The symmetry function requires perfect symmetry. If you engage the feature to an imperfect shape, it will not work as designed. Therefore, make sure that you either use it from the beginning of your modeling or, if wanted later on, delete half your model>duplicate with symmetery>weld the objects together and then engage the Symmetry function again.
