Everything can be created manually but there are also Wizards for automatically creating Components, Schematic Symbols and PCB Footprints.
The wizards are a good starting point while learning Easy-PC. Once familiar with the product, you may decide to not use one of these. That is fine, you can mix and match which methods of the manual and automatic ones available as you like. The same library items are generated by Wizards and by the 'manual' methods. You can often use the Wizards to do the bulk of the work in generating the basic item, then finish off with manual editing to add the fine details.
The Wizards are available on the File menu under New and Wizards. They are also more readily available on the toolbar as toolbar icons to select.
