Discarded passes

I am trying to creat the toolpath for this sign. It is 20" across so it’s kinda big. All the toolpaths work accept the one around the blue area. Does anyone know why this tool path would be discarded.

try to extrude your sketch .125 the then in Manufacturing you should be able to select the surface for your cut plane and all will be there. If not, take a closer look at the lines for gaps and over shoots. trim and extend to fix these issues and try again,
