Looking at these drawings, you would never guess AI drew them
At 1.35am I typed one line to my AI agents: "I'm going to bed. Sort it out. If there's a problem, solve it yourselves." Then I went to sleep.
I wanted a demo UK Building Regulations drawing set: a small extension to a fictional house, in Revit, to the standard of a real sample set I gave it.
By 3.16am the first set of 9 A1 sheets was out. The agents set up the scheme and built the Revit model with existing, demolition and proposed phases. One hour 40 minutes, and no human drew a line.
Then independent AI QA agents checked the drawings through the night. P02 came out at 4.59am, P03 at 7.09am. Revit crashed twice; the AI traced the cause itself (a view created outside a transaction) and carried on.
The best moment: QA caught a real design flaw. Bedroom 2's escape window sat right over the new roof. The AI read Approved Document B and redesigned the scheme around a protected stair. Every regulation note was fact-checked against the official sources. It also made photoreal renders for my portfolio, labelled as AI.

So, is AI replacing us?
Honestly, the full set took about 19 hours and 9 rounds of fixes. Around 90% of the time went on fixing, not drawing, and some fixes created new errors. I had to step in several times: match the sample's sheet composition, cut annotations that read like essays, use keynotes and door and window tags.
The Checked and Approved boxes are still blank. I sign, not the AI.
What gets replaced is the drawing, not the responsibility.
Would you use a drawing set that was drawn while its architect slept? Tell me what you think in the comments.
