a few versions ago gave us "PROFILES"
we can design any profile we want and put them on many components
like roofs, wall siding, moldings, etc, etc, etc.
showing an example using it for wall siding (in wall definition - at end)
and on roof edges - create your roof profile and add it when
editing the "roof edge".
the profiles you create are limited by your imagination.
