OK, I was sure to have tried wireframe after reading your coment, really sorry and thank you for your fast and precise help !

I tried automatic, manual, square points, I also changed sizes and parameters and nothing created the tabs, then I tried to import the file in another pc and it didn't work anymore but creating a new contour on this pc work. I attached the file, if someone want to check settings (most are defaults)... TT.MCX-6

OK, I didn't understand this parameter now I do, thanks. (sorry for posting in wrong thread, tried to find the better one)

Hi, I am using 3d facing operation and my problem is that depth cuts option is used only inside the model vertical bounds. Say I have a stock going from 0 to 10 (in Z) and a model from 0 to 5, if I set a depth cuts of 1 then the toolpath will go directly to 5 and then 4, 3, 2, 1. But it should do 9, 7, 6... Is it a bug, or how can I force it ? Thanks

Hello, I have an issue with mastercam x6, I created a simple model and added some machining operation, but the tabs don't add in 2d contour. I tried several paramaters and got no errors but there's no tab at all. I am a beginner but I already added tabs succefully, then here I don't understand. Thanks
