I'm trying to make a logo and I'm having trouble cutting out part of a line. I'm trying to use an opacity mask to do this because using the pathfinder tool changes how the lines look. The problem I'm having is for some reason my mask is not fully hiding the line.
(semi-transparent line through middle should not be visible)
I have checked to see if opacity or color were the problem and they don't appear to be.
Help would be greatly appreciated.
