Building through layouts
Building with layouts will help you create multiple content structures. You will find the layouts by clicking on the layouts tab on the Assets and Layouts panel. Users can simply drag and drop layouts to the desired section: these layouts will allow you to simply include text and images in the distribution options portrayed with the orange icons.
Here is an example of multiple layouts combined:
Depending on the channel chosen (Email, iPad, Banner etc.) the central art-board of Assembler will show different sections based on a standard structure. Keep in mind to drag and drop your layout in the corresponding one. The sections that you do not use will be invisible in your final job, you can check it in the Preview option before finishing up.
