Hello friends ! I have a simply duplicate Problem. I only want to duplicate a nurbs-object as a mirror object. Here is my file to download: https://www.tophunter.at/3dproblems/spitfire.rar Hmm I know that I can make the following: Edit-->Duplicate-->and in the options I set the value -1 for the right axe but it will not work, so I thought I will give you the full scene file to download and to take a look on it. thank you soo mch for every help, bernhard
