I am trying to make the path of the letters in 'hanwell' trim to/flush with the edges of the bridge illustration, so that the letters only appear in the gaps between the bridge pillars.
I have drawn a bridge using the pen tool and shapes, all parts of it are all on the same layer.
On a new layer I then expanded the type, selected both the type and the bridge, and clicked 'unite' on the Pathfinder Panel.
This nearly did what I wanted, but a strange horizontal line appeared, ruining it. Can anyone explain where this line has come from and how I can get rid of it?
To try and figure where this infuriating line was coming from, I tried getting rid of the text, selecting just the bridge and clicking unite, and it appeared again, which suggests to me that the problem is something to do with the bridge illustration and not the text.
As per the suggestion from a kind helper, I have also included what I get if I press show outlines (before I press unite) - strangely the rogue line doesn't show up.
