I have a bunch of lines that go behind the layer of a mountain that I have created and I would like to cut them out. Proving to be impossible right now with the pathfinder tool. Any suggestions?
Assuming the yellow needs to be removed from the mountain.
Select the yellow and choose
Object > Expand from the menu. This converts the strokes to shapes. Pathfinder doesn’t work well with strokes, it needs shapes.
Once the strokes are expanded you should be able to use Pathfinder to subtract the yellow shapes from the mountain (or anything else).
