Roofs on the A Roof2 layers. Gutters (on F Gutter). Top elements of chimneys on A Fireplace or A Roof2. Notes on +A Arch Note Reg Scale. +A Misc Line. The roof plan uses the same layer combination for output as the rest of the plans, A1 Floor+Roof Plan.
Roof elements will be placed on the lowest story on which they should be visible, and they need to show enough stories above to be visible on the roof story. For some roofs this means 'one story up', and for some it means 'all stories above' (custom setting). Much more on roofs in plan here.
• Annotations.
For the slope arrow, use a line with an arrowhead at one end. The arrow points down.
Note the roof materials, gutters, crickets, etc.
