Upon purchasing the item you will receive links to a file, Moody's Louvered Shutters.

To use "Moody's Louvered Shutters" you should append it to a file. Append the collection, "Moody's Louvered Shutters".

Once you append the collection you should hide the collection within it called, "Shutter Parts". This collection contains the building block for the cathedral shutter style, and it should be hidden.

You will have two shutters that are centered around a pivot point. If your window has a pivot point at it's center you can just move the cursor to selected (Shift S), then select the shutters and move selected to cursor.

Then choose "Width" to move your shutters to the correct width.

Adjust the Height with "Height". The shutters should go up to the bottom part of the upper sill.

Then adjust the height of the middle board using "Middle Board Position" until it is roughly in line with, or a little bit above, the divider point of the two sash windows.

You can choose between a "straight style" or a "cathedral style" at any time.

There are many other settings with "Moody's Louvered Shutters" that you should explore on your own, but the above will get you going. I also have a YouTube tutorial on the shutters.
