Originally posted by mtmckinley couldn't you just select the faces you want to smooth and smooth them? Why would you need to extract? Just curious. On my helicopter model, if you smoothed any faces, you would get dark streaks everywhere. Since I don't know a thing about normals, I used my smoothing method, which resulted in no dark streaks. I would have told Dann to mess with the normals, but he already had, so I assumed he needed a different way around the problem. If modifying the normals like Danny says works, then smoothing will become very easy for me. I really don't know all that much about normals, which is why I did what I did.
