Find mistakes in building plans.
A door is drawn but missing from the door list. A room has two different measurements. Equipment needs power, but no connection is shown. Mebbian points out these mistakes for your team to check before pricing or sending the plans.
What AI drawing review catches
A floor plan may show a door that the door list leaves out. Someone pricing from the list could miss that door. Here are other examples Mebbian checks for.
Missing pages or explanations
- A note points to a drawing or page that is missing
- The page list does not match the page titles
- A numbered note has no explanation
Doors or equipment missing from a list
- A door or window appears in the drawing but is missing from the list
- Different drawings or lists show different sizes or counts
- Different teams use different names or numbers for the same room
Equipment without a shown power connection
- Equipment needs power, but the electrical plan does not show a supply
- The equipment needs a different power supply from the one shown
- The drawing shows a circuit that is missing from the electrical panel list
Missing sizes or different product names
- Measurements do not add up, or important measurements are missing
- The size of a beam or connection is missing
- Drawings and written requirements name different products
- Work is marked 'by others' without saying who will do it

How to judge any AI drawing review tool
- 01
Test it on a set you already know
Send drawings your team has already reviewed or built. You know the real mistakes, so you can see what the tool catches and what it misses.
- 02
Check that every finding shows its source
Each finding should name the sheet and quote the drawing, so a reviewer can confirm it in seconds against the PDF.
- 03
Check for repeated or incorrect warnings
A useful review lists each problem once across the whole set and puts the costliest first. A long list of repeated flags costs more review time than it saves.
- 04
Ask what happens to your drawings
Find out where the files are stored, who can open them, when they are deleted, and whether they train a model for anyone else.
- 05
Keep the decisions with your team
The tool should suggest questions. Your qualified team should check the answers and decide what to send.
How Mebbian reviews a drawing set

Your company brain keeps your firm’s project knowledge, rules and past decisions. Mebbian uses that knowledge when it checks new plans.
