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, you will find the "Shutter Mechanism" option. This option may be available under both the "Quick Access" section and the "Construction" section, making it convenient for you to access.

Click on the drop down menu to access the various options available of different shutter mechanisms like swing, double, lift-up, flap down etc.

Select the required option and the same will be changed in your selected cabinet.
