why boolean not working with other modifier I have just a normal mesh and added 2 mirror modifier and 1 solidify modifier and with the boolean modifier its not getting difference. May i know the reason why its not cutting the hole. I check the doubles, normals yet to its not working. Any suggestion or help. Thanks
You have fill "Only Rim" enabled.  This fails to draw anything but the rim.  In other words you're trying to Boolean Difference a single plane.  Difference is calculated based on normals.
