[Gmsh] periodic BCs

To All;
What is the method used to generate a mesh for a periodic BC?
Specifically, my problem is 180 degree periodic about the Z axis, so the surface mesh at Y=0 needs to be mirrored; for each node (x, y=0, z) there would be a matching node (-x, y=0, z).
Of course, I'd like to do this with arbitrary rotation or arbitrary translation. If I could select my plane, do a TRI mesh, copy the plane to the new position along with it's accompanying mesh and follow that with a TET mesh operation, I think I'd have exactly what I was looking for. The issue is whether meshes can be copied within GMSH, or whether I have to generate the TRI mesh, use a separate program to duplicate it and follow that with a 3-D TET generation.
Regards,
...Dan
