NX API - CAM - How can you determine if thread mill operation is ID or OD?
Solution
The difference between the two operation types is in the (in process-) feature type, being NXHOLETHREAD / NXBOSSTHREAD . Same for hole milling (NXHOLE / NXBOSS)
In NXOpen, call GetInProcessFeatureType on the thread milling operation (NXString Operation::GetInProcessFeatureType) and you will get the string NXHOLETHREAD or NXBOSSTHREAD .
