I want to cut square faces around this part. But Circular Pattern (Cut-Extrude2 in tree) is not cutting certain faces. How to fix this?
The problem is that your Chamfer is not accurate enough. For the circular pattern to work the all the faces need to be tangent to the same circle & as you can see from the image below yours are not.
Once the chamfer was adjusted it worked fine:
It will work as you had it but you need to have a blind cut & turn off Geometry Pattern.
I cannot open because of future version, but perhaps try a blind depth cut instead of up to next?
I tried that but result is same.
You could just make the blind cut deeper. Really you could make them "through all". It seems, though, that you expect a consistent wall thickness but your model didn't achieve that.
Try instead of cutting it with a feature to use combine.
Create a Boss Extrude as a separate body, Circular Pattern it and then use combine bodies.
Not the wall thickness is the problem … it's the edge length!
While the one edge of the part is 1" (25,4mm), the other - chamfered edge - results in a length of 26.9408mm. And therefor the circular pattern feature fails. It would work, if both edges are the same...
So you have to adjust the main dimensions or/and the chamfer dimension.
And here it is.

Excellent deduction, Kevin! I'm glad this was marked as the correct answer as it should help others that happen to search and find this.
There is an issue. I used already created axis (Z) in my template for circular pattern. At the same time I tried with new Axis1 created for this purpose but it gives me correct result.
I checked both axis and found small deviation. So that template axis is not reliable. What do you thing?
"Measure" finds NO deviation. What YOU have found is a inaccuracy in the graphics. When i had a look in the Document Properties / Image Quality / Deviation, it is around 0,033 although the setting is really high. The graphics resolution is never that high, as the calculation precision is.
So it's not really a big deal...
So why a change in axis alter the final result?
I have found no change...
The only difference is the direction of the axis. So if you use other setting and change the axis in the pattern feature, you will find some change in direction.
