Symmetry without screwing up UV's

[Wegg]

The way it works in Lightwave is that you select an axis to mirror. . . and if the modeler finds a corresponding point/edge/face on the mirror side, then it will manipulate that side in the exact same way. The behavior is exactly the same as Wings' Virtual mirror but without having to slice the object in half (blowing away half the faces). Having intact UV's because of this behavior is really just a bi-product of that workflow. I can make a video for you if you'd like.
