Pro/ENGINEER entities are assigned pens based on the default system colour corresponding to entity type. When entities are plotted, the system uses the line width and line font associated with a particular colour. For example, all entities that appear in Pro/ENGINEER in white are plotted to pen #1, and have the same line width and thickness.
