Hey that's a good question
@MacClarkNC. Do map drawers still exist?
Since everything is digital, the only professional use I can think of for them is archived historic sheets, and even those have been digitized for safe keeping...
Yes, some people here will cut templates to save, for in case they ever want to build a specific plane again. Map drawers could be quite useful. Me, as long as I can get to a printer I'm happy.
