Drawing detective.
Every drawing gets checked before it leaves the office — because a small mistake on paper becomes a big one on site. This sheet has six problems a checker would catch. Click every one you can spot — a few things are perfectly fine, to keep you honest.

- Scale doesn’t match. The title block says 1:50 but a note says the plan was drawn at 1:100. Which is right? Never leave it ambiguous.
- No north arrow. Without orientation, nobody knows which way the plan actually faces.
- The dimensions don’t add up. 2000 + 2000 is 4000, not 4500. A checker always totals the runs.
- Spelling: “BADROOM”. It should read “BEDROOM”. Sloppy labels make people doubt the whole drawing.
- “Scale off drawing for sizes.” Bad practice — you should never scale real sizes off a drawing. Use the figured dimensions. It should say “Do not scale”.
- No revision. A drawing “issued for construction” must carry a revision, so everyone builds from the same version.
