I was told by an experienced repairman/carpenter that there are 2 kinds of skylights. Those which haven't leaked or had problems yet, and .... yeah.
But they're so cool! Although nowadays, I guess somebody could park a drone above your skylight and have a partial view of the inside of your place.. hehe.
No skylights here. Those are just vents and such on the roof. I want to be fairly accurate though with things incase a reno comes up where i need to know the placement of this or that.
Cool, my dad was a draughtsman, he worked with autocad as it came into use back in the 80s and such. He worked for the provincial govt power company "BC Hydro". In his early years it was all pencils, rulers, slides, erasers, and other analog tools.
