Unable to hide sketch origin points
This was a known issue starting in NX 2000 and has been resolved in NX 2206. Any sketch that was created before NX 2206 with this problem, will need to have the following workaround applied:
Activate this sketch using Edit with Rollback. Once you are inside the sketch, create a line and delete this line right away and finish the sketch. After you are outside the sketch, you'll see that the sketch origin point(s) will be invisible.
