I was advised to use a library feature instead of a forming tool in This post

But it seems I can not sketch pattern this library feature.
Am I doing something stupid again?
Both library feature and a sample file is attached.

Any kind of advice is much appreciated.

Sorry, it's a future version file for me. So, I can't help.
@HerrTick, @gupta9665, @jcapriotti any of you have time for this?

I don't have 2021 installed.

@Tera You are inserting the library feature, then doing a sketch driven feature pattern after?

I tested it, and it is fine as long as your sketch locating the library feature is separate from the sketch used to pattern. IOW, you'll need two sketches: one to locate the feature, and another to drive the pattern.

Per Mike... it works. You can't share the same point you had.. it piled on the feature on a feature. (image)

That works, but you can also change the library feature so that a single sketch will work. The root cause seems to be the fact that the extrude sketch and the cut sketch are on the same plane. If you change the library feature to do the extrude first, and then use the end face of the extrude for the cut sketch (using Offset of course), the pattern will work using a single sketch:
This has nothing to do with library features by the way. You can dissolve the library feature and you will have the same problem.

I really appreciate everyone's help.
Million thanks.
