Review New Model View Options for Fills
The Model View Options panel, formerly called “Options for Fills and Zones,” is now called “Override Fill Display.” As in earlier versions (ARCHICAD 11 or earlier), this panel is used to globally define the Fill Backgrounds, the display of Cut, Cover, and Drafting Fills, and the display of Zone Fills in the project.
The various options have changed somewhat, but when you migrate an older-version file to ARCHICAD 19, the program will assign corresponding Model View Options to ensure that fills are displayed correctly in ARCHICAD 19. However, you should double-check the fill display in ARCHICAD 19 and make any adjustments necessary.
