The predefined Pen Sets shipped with ARCHICAD are based on common workflows.
See Predefined Pen Sets for Specific Functions for an overview of the logic behind predefined pen sets.
However, you can use the Pens & Colors Dialog Box to
•redefine or rename any pen set together with its description
•redefine any pen’s line weight or color, using the Edit Color control
Pen numbers remain constant even if you change pen sets.
After redefining a color or changing the Pen Set, the ARCHICAD construction elements immediately change to the new colors on the Floor Plan. The 3D window, 3D Document and Section/Elevation/IE/Worksheet windows may require that you rebuild the view.
