Illustrator paths problem

Hi guys, i have a little problem here. I’m pretty new to Illustrator and I’m just learning by myself with the tuts+ tutorials and video courses.

I have a little flat graphic here I’m working on for practice and I don’t understand why there is still some kind of border. U can see it on the picture here

I know its not really a border but the graphic (blue circle) under the hill shape I created there.

QUESTION IS: why is it still visible if I used the pathfinder? it should be pixel-perfect matching? If i check on graphicriver for such illustrations I don’t see such 0.01pt overlay.

Any tips or advice for a starter like me?

hi, u can make two different things … select the concerned path and take out the points until u get rid of the shape, otherwise, u can choose to create a new shape on top of it and merge it with the white shape so that u can get rid of the unwanted flaw …

Yeah, why not use pathfinder on the blue half circle using the snowed mountains instead of overlay it…CMIIW

Thanks for the tips. I thought about that last solution too, just changing the blue circle.

But I thought maybe this is a settings thing. I mean a program like the latest version of illustrator is not able to create pixel perfect shapes when using the pathfinder the way I do?

Also the last suggested solution would lead to the same effect, wouldn’t it? Then there would be a 0.01pt wide gap between the hills and the blue background shape. It would just need the right colors and it would be visible again.

:confused::confused::confused:

hm no one with another solution? you guys are sure this is not a settings thing in illustrator? :confused:

I get this with every shape I create with illustrator.
