Tool Path Visualization 'Replay' of a Turning Grooving operation gives incorrect 2D material removal. (material shows the offset by 2 x the tool radius)
Solution
The problem is fixed in NX 1863 - May 2019 Monthly Update (NX 1847 Series)
A workaround in NX 12.0.2 is to toggle the Tool Display to 'Assembly' (without stepping through the operation) and back again to 'Part'.
This clears the problem.
