The Project Explorer can be customized using the Preferences and Layout options within the platform.
Preferences determine any aspect of the Project Explorer user interface which is not relevant to the generation of reports. For example, color schemes and default scale settings for profile and section views, font settings for the user interface, and the visibility and pane layout of each individual Object Category tab in the Project Explorer window.
Layout Options determine the layout, format, heading name, and visibility of data columns and values in the Project Explorer user interface and in generated reports, spreadsheets, and AutoCAD tables.
