Skylights are defined by their width, height, and trim size. You can edit the properties before you draw or after the component has been added to your design by selecting it and clicking the Properties tab in the right sidebar.

Skylight Style lets you choose the type of skylight you want to add to your roof.

The Custom Skylight style includes a number of additional categories to choose from.

Width defines the distance from one side of the skylight to the other.

Height defines the distance from the bottom of the skylight to the top.

Trim defines the width of the trim around the skylight. This is not included in the overall height or width.
