: Intersecting Paths in Illustrator leave a residue In figure 1, the black shape represents the result of intersecting the yellow circle and the gray shape. If I zoom it to 64k%, as shown in

Setting the precision to 0.001 pt in the pathfinder panel options worked for me. By default, the value is set to 0.028 pt which I figured isn't optimal.

Thanks to Tom Frederiks for the answer.

My first guess is that, while zoomed in, you have the shape selected, which outlines it with the color of the layer that it's in. Your default layer color may coincidentally match the color of the solid you're intersecting. (See images below.) Changing the shapes' colors can help you easily discover if this is the case. You can also change a layer's color by double clicking on it in the layers panel.




The intersect function of the pathfinder tool is only supposed to leave one shape after two are intersected. Could you show us the actual result of the intersection of your two shapes as well as the example you put together?

If it's not the first case, I would try ungrouping and releasing any compound paths with the result of the intersection selected, then look in the layers panel for any shapes that may have been unintentionally created. Also look in the styles panel to see if the result has a stroke on it. Sometimes using the pathfinder tool can cause the resulting shape(s) to inherit styles from one of the shapes used to create it.
