rectangular array of circular array

[RonnyC]

Hello fellow NX'ers

I 'm encountering a slight problem when making a rectangular array of a circular array of a hole. (NX5)
The model is a pipe with perforation holes in, I modeled 1 hole and made a number of repetitions (value A) around the circumference using circular array. This circular pattern needs to be repeated B times along the length of the pipe using rectangular array.

This works fine, until you increase value A (number of repetitions around the circumference).
The rectangular array doesn't include the newly created instances of the circular array.
Problem is, I wanted to make a user-defined-feature with these features included, so it needs to be fully parameterized.

Does anyone have a better idea how to do this?
See example file attached.

thx,
Ronny

Create the circular and the rectangular array using the Instance Geometry feature ( = array Points over the cylinder), then using the NX5-new hole type place the holes using selection method "Feature Points".
The selection method "Feature points" is the trick, else the holes will only apply to the number of points / or fewer points that existed when the holes was created, Selecting the points by "single point" will map each hole to an individual ID of that point and because of that the array cannot increase the number of members.
