When you select a style, all of the properties in that style are copied to the instances of element created with that style. When you start the program the element types are displayed with their default properties as saved in the default style.
Styles are managed in three levels. The three levels are Local (Project only), My and Factory. Optionally you can work with another level called Loadable package of styles.
Styles created and saved in a project are included in this category. Please be aware that these styles are not available in other projects. These styles are denoted by blue upside down envelope icon. It is a good idea to create a local style if you do not plan to use the style again in another project.
Your favourite styles are stored here in order to make those available in every project. My styles are distinguished from other categories by a human shape icon.

Factory (built-in) styles come with the installation of the software. These styles have read only property you cannot change them. These built-in styles are represented by orange envelope icon.
