Hello, no, I don't think I explained myself well. I have a model that I want to be symmetrical - but it isn't. Somewhere along the road some of the vertices on one side have gotten out of alignment. I want it to be perfectly symmetrical. I've started UV mapping though so really don't want to delete half. According to the help files, I should be able to select the vertices on one side, and transfer the position by selecting Edit Mesh > Transfer Attributes, selecting "Vertex Position" and "X" under "Mirroring", but nothing happens at all. It's not something I've had to do before - but I'm hoping you or somebody has! thanks, gubar
