Is there a symmetry script?

Hi, I was wondering if there is a script to model mesh with symmetry without having to cut a mesh in half or selecting both verts on both sides (s key). Like on this script where you put the mesh right on the center and automatically mirrors the other side but without the sculpt mesh feature so I can edit it only the verts I select.

try reading this: http://download.blender.org/documentation/htmlI/x3517.html

Is that what you want to do?

Just try my ‘ph_symmetrise_mesh.py’, you can find it here:
