I’ve used Intersection and Difference to edit paths forever. Two months ago I wrote a brief tutorial on how to break up designs. I’ve used this technique for a long time. Now, it no longer works on anything but simple shapes.
For example, if I overlay the rectangle over the circle, and select “intersection”, the overlapping part remains. In the past, if I overlay the rectangle over a portion of the text, only that portion of the text would remain. Now it has no effect.
What the heck could be going on? Image shows all objects are paths.
