I am currently trying to make a 5 gang box faceplate for 5 drok meters to measure power. I was able to use the boolean tool to cut out the screw holes and one of the meter inserts. However, when I use the boolean tool again to try and cut the other 1.5 slots, it fails to cut my main object and the previous cut will fill back in. I have also tried making a cube to size vs my "cookie cutter shape" and it fails as well. What am I doing wrong and is there a better way to cut this?
Boolean modifiers will only work with manifold geometry and right face orientation.
You can check your face orientation here:
So click "viewport overlays" and check "face orientation".
Blue means: ok, red means: wrong face orientation.
You can repair this by selecting the meshes which are red, TAB -> edit mode -> A (select all) -> SHIFT-N -> recalculates normals. Then the mesh should turn blue.
After you repaired all your meshed, and it still won't work, pls upload your repaired blend file. Thanks.
