Thanks for replying,
I have tried using the 2d sketch of the gear wheel directly into the CAM section. Reasoning that with no thickness in the Z plane the programme can only see a profile. The same thing happens, low numbered tooth gears work while high numbered gears fail. In that the programme will only pick individual lines be it root, flank or tip. By experimentation I have discovered the magic number is 39 teeth. 39 and lower gives a profile and higher, starting at 40t, fail.

If you want to look at the problem I have attached two files. 32t 8DP shows a successful tool path creation for cutting the teeth and the rest of the profile. 40t 8DP shows an incomplete tool path because of this problem

Thanks for your time,

Frank
