What's going on with Illustrator that adds so many anchor points when you expand/outline a path? This is the result I used to get before and then how it behaves now. Why does it need so many ancho points for a simple circle?
It does it with all the shapes regardless of how simple they are, like 6 for a triangle now?

Hi @Piter1288, that's really weird! I'm not able to reproduce that though (MacOS AI v26.0.2).
Are you working with a simple appearance? For testing purposes, please press D for default appearance and choose Object > Path > Outline stroke. Does that give too many points also?
Well, that's even worse:
Weird, but why is the circle red? When I press D it sets fill to White and Stroke to Black. Is your default different?
I did change the color before creating the circle so the anchor points will highlight better, I posted a little video about what I did.
that's weird indeed, but I did notice your shape is rather large, so digging a little I was finally able to replicate your problem
expanding a 425 pt diameter circle = 4 points
expanding a 426 pt diameter circle = a few more points
expanding larger circles = more points
Good detective work Carlos! I can confirm the same on my system. I wonder what the reason is. I did notice there is a 1.5pt difference in the shape of the curve when comparing a 10,000pt expanded circle with a 10pt expanded circle scaled up to 10,000pt (it keeps the normal 4 points). So very minor. Interesting.
>>I wonder what the reason is.
It did the same on my second test on a 4K video profile. I suspect it is to maintain the integrity of the shape.
And we have a winner! Yes, that reason, I checked that it does this if the circle is higher than 300 x 300 px. Here's a comparison between a 100 px vs a 500 px:
Now it surprises that the handlers cannot reach higher and it needs to add up to 30 anchor points to keep the shape.
Hi Mark, I did notice scaling a small circle up doesn't add more anchor points. I have no idea what's going on.
About size difference, there's another related thread. A user reported that rotating a circle changed its dimensions. The issue could be related to the "circles not being real circles but Bezier approximations" discussion.
Now, regardless of the size, if your circle is in rotation you will end up with extra points as well. These are less than 100 px circles:
I'm getting the same results as Mark. I'm on Windows 11.
can you describe what you're doing exactly to try to replicate it?
I'm at a loss. Anything unusual show up in the appearance panel? Running a beta version of Illustrator? Done a restart? Sorry.
This is my appearance panel:
I'm not on any beta version, yes, I did restart my computer, plus I don't use any type of extension that could be messing things up.
Does AI have any clear cache function? It's the only thing that I can think of. What I'm 100% sure is that it didn't happen before, cause it would've caught my attention for sure.
What keyboard command are you doing to display the anchor points? I don't see you switching tools and want to confirm your method.
Hi David! I use Windows, so just hit on the Ctrl key to display them.
