yes sorry about that, actually i am showing that i wanted to make a cut out using two small rectangle box 2nd image is the box i am using for boolean, 1st image shows that applying boolean makes a cut out of the box in wireframe, but if you can see in 3rd image the boolen isn’t working in solid mode, and 4th image to show there isnt any double mesh so not sure why its not working, ps – in 2nd image i have used boolean at the side too to make curve cut out for the knob that seems to be working overall.
