Hello people.
For those who are on slightly older versions of NX like me who still need to use datums in order to put holes through a curved surface, I have attached a model which will hopefully show you how you can create a hole which pierces surface normal to the face regardles of what you do to the controling expression. Suppress all the features and look through them one at a time.
The important bits start with the HOLE POS sketch consisting of 1 single reference line. The length of the line is controled by a named expression called PCD.
I exited the sketch and added an associative point ot the end of the line and then projected that downwards normal to the surace of the revolved face. I then added another datum (type: point and direction) using the 2 poiint option of the drop down menu within the datum command and the associatice and project points to define the plane normal.
Then simply add a hole to the datum and position it point onto point of the projected point and create your circular array.
Open the expression editor and modify the PCD expression between 300 and 60 and notice that the hole will always be normal to the face.
Enjoy.
Best regards

Life shouldn't be measured by the number of breaths you take, but by the number of times when it's taken away...
