This hair artwork is composed of dozens of paths.
A path (which has been Brought to Front) represents the hair parting. I'd like to delete this path, so there is a transparent area there. (This is so the hair can be overlaid on artwork of bodies of differing skin tones.)
When I select all the paths and click Minus Front in the Pathfinder panel, I get this:
I must be misusing the tool, but I don't understand how. I have tried both grouping and ungrouping all the paths beneath the parting layer, and moving the parting onto a higher layer than all the hair paths, but it still has the same result.
