Patterning feature - erradic behavior

Hi !

I'm new to fusion 360 and I'm trying to recreate some wiper linkage bushing (https://www.amazon.ca/Dorman-49447-Windshield-Linkage-Assortment/dp/B000IWFPIW the 3 middles ones).

I provided a screenshot of about what I'm looking for. TLDR: Merge both cuts in the squared green boxes (they are on the border only, the inner is empty) and put it where my blue squares (Snaps) are. My screen shot currently use a 3x repeat pattern.

WARNING: You can't see it on the screenshot but the outer of the "Snaps" is slightly below the round ring at the top, so I will probably need to do this cut action twice (one for the "Snaps" component" and the other for the remaining bodies".

So my issue is if I use the circle pattern for 4x repeat on the extrude cut it won't cut through the main body (the green squared in the middle), but if I do use the value like 3 (in the screenshot) then it go through.

Have you any idea of who I can achieve that?

Also, I'm welcome with any design best practice.

Thanks

Change Compute Option to Identical - worked for me.

Might help...

Which is correct:

@etfrench

The first one, I did create one pattern using 2 extrudes cut to do the job.

I guess you are using the compute option "identical" as well?

How to look like a retard in one easy step... thanks!

I did test it beforehand but I guess I didn't retest it in with this specific history.
