Formatting Entities
Use the formatting galleries to set the line font and color of entities in a layout. You can choose from a list of standard line fonts, or from recently used, standard, or system colors to apply to new or selected entities. System colors correspond to system-defined entity types and update according to their associated settings in the System Appearance area of the Creo Parametric Options dialog box.
