Details
When creating Threaded Holes with the same diameter, opposite to each other, NX fails to properly display the threads from both holes, as one hole consumes the cylindrical face of the other.
Solution
No solution for now, ER 7670823 is submitted to ask for this functionality.
Work around :
Create Simple Holes and add Symbolic Thread on the opposite sides, this will properly display the thread in Modeling and Drafting.
