What this command does
The Atrium command lets you cut out a portion of the roof along an eave to create an atrium.
You can also use it to create a drop-down.
How to use Atrium
Select Mod-Roof > Atrium.
When prompted, select the eave line you want to modify.
The Atrium defaults dialog opens. Enter the atrium parameters (see below).
Confirm your settings to apply the cut-out.
Atrium defaults (what each setting means)
Distance along eave

Measured along the eave from the end closest to where you selected the eave.
For reference, that end begins to flash.
Atrium width

Atrium depth
