Begin by selecting the cabinet that you want to change the shutter mechanism for.
Look for the menu labeled "Shutter Systems" on the right of the design panel. It would be arranged in a vertical order as Cabinet>Partition>Shutter System>Shutter> Panel etc. Click on it to access the settings related to shutter systems.
Within the "Shutter Systems" menu, go into the "Construction" tab and you will find the "Toggle opening direction" option.
Click on the same to change the direction of the opening or location of the hinge of the shutter.
