I noticed something strange in NX10.02. MP6 while simulating a turning operation with CSE.
The inner diameter get smaller! You can use analyse tools to check the diameter.
For reproducing take the sim11_turn_2ax CAM-Part and simulate a turning operation.
It is a bug? I can't find a PR for it.
Please provide more information, it is hardly possible to give a statement without some more data info pictures.
Alternatively I like to ask you if it is possible to test in NX10.0.3 MP1 . If the problem still occurs please get in contact with GTAC.
