Rookie65 you are correct. I set it up properly in drawing sheet and layout but, the HD-Pro 2020 does not allow print/PDF generation beyond 18" x 24". Tech support confirmed. Upgraded to HD Pro2021 and it worked!

Started in print settings: drawing sheet set-up: custom then made a size called "Arch-D (24" x 36") put the size in the width/height and left setting at 1" = 1" All looks good when I select it as my new saved layout but, when I go to export as a PDF I get a black sheet at 24" x 36" ... select any other paper size other than my new Arch-D (24" x 36") and everything shows up ? What am I missing here? Chuck HD Pro 20

Good question... I as well am looking to work with D-size. Have not figured out how to change this in Default. Chuck Home Designer Pro 2020 Mac
