I have a circle 'shape' I'm trying to cut into a crescent shape. The thing is this 'shape' is made up of non intersecting lines - as you can see in the attached file.
Prior to using minus back on the combined shapes ie. the line shape and cutter shape - I've tried grouping, expanding and forming the line shape into a compound path.
Then, having combined the line shape and the circle that will cut the crescent shape from the line shape, I use minus back in pathfinder. The result always seems to be the same - the line shape disappears.
Can anyone tell me how to fix this please ?
Here is a visual of what I'm trying to do.
