Each project you create will comprise a mixture of pages depending on the nature of the project. Normally this would include the cover page, contents page, wiring line diagrams (also called single line diagrams or synoptics), schematics, reports and 2D cabinet layouts. The first 4 types of page are added by default (one of each) when you create a project.
New pages can be added easily by right clicking on an item in the documents browser, selecting "New" and then choosing the type of page you want to create. The exception to this is if you want to add a 2D cabinet layout. To do this go to "Process" and click on the "+ 2D cabinet layout" button. Reports are created automatically (see "Project" > "Reports"), including the Bill of Materials, but can be exported from projects and accessed via hyperlink.
