So that you avoid dealing with so many fills at a time, the Fill chooser pop-ups, located in dialog boxes throughout the ARCHICAD interface, do not contain the full set of all project fills – only those fills which belong to a category that makes sense in that context.
Open the Options > Element Attributes > Fill Types dialog box and view the Fill Availability and Screen-Only Pattern panel.
In the Fill Types dialog box, you can freely edit the availability, by Fill Category, of any fill type.
Note: There are some restrictions. For example, Image Fills cannot be used as cut fills.
