Cutting a zigzag line
Hello everyone!
Can someone help me please?
I need to cut the waves on the left side on the orange circle and on the right side on the red circle and the waves need to stay symmetrical.
I tried to put anchorpoints where the lines and the circle cross, but when I delete the outer anchor points, the waves change and it's not symmetrical anymore.
When I tried it with the pathfinder the waves just disappear.
Thank you in advance!
