How do I change my settings so that when i change the angle of my cabinets with the rotating icon, it dosent go by 1 degrees but 15 degrees and snaps

Hello, After I put lights everywhere including rope lighting, and lighting in cabinets I need and it is time to take pictures for the client and I use the Cross Section Slider , some lights are on, and some lights are off? Anyone have any suggestions. Is there maybe any specific lighting to use inside glass cabinets?
