You will primarily work with the Editor Windows while desigining your cover. Each Editor Window represents the side of a cover model such as the front side, top side, spine side and so on.
The number of Editor Windows that opens up will depend on the type of cover you are working with, i.e Two Sided Box opens up two Editor Windows, Three Sided Box opens up three Editor Windows etc.
In this example it’s the front side of a Three Sided Box cover, sized 350×400 pixels.
Certain menu items such as the Delete, Copy, Cut, Move to Front and Move to Back are only active when you have a layer selected.
Printing Editor Window Content
To print the 3D cover image though, you need to use the 3D Print button on the 3D Setting.
