Adding Features to a Rectangular Pattern
Adding Features to a Rectangular Pattern
(OP)
I am using NX 7.5. I have a rectangular pattern of an extrude feature (round hole). I added four tapped holes (one hole feature and a rectangular pattern to creat the other three) around the original circular hole. Now, I want to add these four new tapped holes to the existing rectangular pattern. When I right-click on the pattern in the tree, the only option that looks like what I need is "Replace", which I can't get to work.
Any ideas out there?

RE: Adding Features to a Rectangular Pattern
The best that you can do in NX 7.5 is to create a single hole, create the bolt circle around it and then do a rectangular instance of the 5 holes.

Is there a way to get from what he has now, to what you're suggesting?
Can you 'add' features to an existing pattern?

RE: Adding Features to a Rectangular Pattern
You can't add the new hole pattern into the existing feature array, but if you create it in the other order, you can array the array.
So:
1. create the first hole
2. create the second hole (tapped), and then array it around the first
3. create your second array, and select the first hole, plus the 4 instances of the second hole
That works fine (the preview looks rubbish but hit ok anyway and its good).

RE: Adding Features to a Rectangular Pattern
So:
1. create a sketch with a point in to locate your first hole
2. use pattern in the sketch to array the point
3. create a second sketch with a point located near the first hole (dimensioned from it if you wish)
4. in the second sketch, use pattern to create a circular array around the first point
5. then, use pattern again to create your linear array of the circular pattern
And that's it.
You can now use the hole command to create your "two" holes, by picking each sketch from the feature navigator as your locator.
I've just created 20 holes of two types using only 4 features.
Finally, if you want to tie the sketches together for updates, create some expressions for count and pitch.
Then go back into the sketches and double click on the pattern constraint to edit it and select the expression.

However, my (and evidently Walterke's) question still remains, can you add features to an existing rectangular array? It sounds like the answer is "no" based on carlharr's response. It seems like such a simple thing, I can do it in Pro/E rather easily.

You can't edit an existing array to add further features to it.
The selection window doesn't pop up - however it's quite an old command (and now obsolete).

However I am pretty sure there is a work around if you think ahead. If you array a feature group you can later reposition newly added features (dragging in timestamp order) to before the feature group, then add them to the feature group, this should update the array.
