Water straight off the boil through thin paper really does taste cleaner, same thing happened when I tried it.

My old boss at a shop in Toledo made us draw every single line too, and I swore blocks would mess up my layer control, so I kept doing it the slow way for years. Then a job came through where the client changed the ceiling height in every room and I spent two full days just fixing hatch patterns on 14 sheets. That was the day I ate my words and built my first wall block. Now I keep a starter file with blocks for walls, doors, and tags, and I copy between sheets without even thinking about it. Copying from an old job works in a pinch but you drag along junk layers and old text styles you forgot were in there. Build your own blocks once and the next 50 jobs pay you back for the afternoon you lost.
