I have a vector version of the Maryland flag (lots of shapes grouped into one rectangle). I want to cut a rectangle out of the centre, to use the flag as a border. I draw a rectangle inside the flag and with both selected, choose minus front from pathfinder but that takes everything away except the bottom right corner. Don't understand why. Do I need to do something else with the grouped objects that make up the flag. Tried to make a compound path but that turned everything yellow (one of the colours in the flag.)
Having difficulty all around with this flag, including making clipping masks to put flag inside shapes. Is there some trick to using a grouped image to make clipping masks or other paths?
