Actually, the trick I did a while back....I recall several of us posted pics, you should check the archives here at the Carrara Forum.... anyhow, I selected the whole surface and used the "add thickness" function, but with "connect polygons" un-clicked. Then I emptied everything and went around by hand connecting the lines, creating new polygons between what had been the old ones. It wasn't, the way I did it, the simplest thing around. I'd give the trasnmapping a whirl first, I would. And you might be able to make that even more impressive by applying bump map or Anything Grooves as well. Not sure why you need actual wires, BTW. You can set up your render preferences in Carrara to just render the wireframe. Can do that in Poser as well (using the "render a movie" settings).
