AI blueprint reader: the title block as data

Drop a blueprint below, as a PDF, a scan, a photo, a DWG or a DXF: Max AI finds the title block and reads its project, sheet number, title, scale, date, revision and author into a sheet you can check and correct on the page. It also names the layers by meaning. The sheet shows in full for free; the export with the CSV, the JSON and the drawing costs $10.

What do you have?Try an example: a vector plan already converted, no upload →

PDF, PNG, JPG, TIFF, DWG or DXF · up to 50 MB · Every mode free, 3 downloads a day · No 3D, no BIM. Texts turned into outlines in the PDF stay lines.

What you get

  1. The title block, foundOn the sheet's border or corner, wherever it sits, on a PDF from CAD, a scan, a photo or a DWG.
  2. Read into fieldsProject, sheet number, title, scale, date, revision, drawn by. A field it can't read stays empty: it never makes one up.
  3. Checked by youEvery field is editable on the page before the export. The export writes your corrected sheet as title_block.csv and title_block.json.
  4. The drawing tooThe plan comes in the same export, its layers named by meaning if you keep the proposals.

How it goes

  1. Drop your fileA scan, a photo of a sheet, a PDF or a CAD drawing, up to 50 MB, no account. Max AI is ticked: untick it for the free conversion only.
  2. The code draws, Max AI readsReal lines, arcs and texts traced first; then Max AI names the layers, reads the title block and looks for the scale. Usually under a minute.
  3. Check, then exportEvery proposal is on the page, the picture watermarked: tick, untick, correct the title block. The export is $10 per drawing.

About the formats

PDF
A PDF exported from CAD software keeps the drawing as vector paths: Vector plan reads them as they are, nothing is traced. A scanned PDF is only a picture of the sheet, so it goes to Scanned plan. We tell you which one you have before you download.
PNG
A lossless image: scans and screenshots keep sharp edges, which gives the cleanest tracing. 200 dpi is enough for most plans; images over 60 megapixels are refused.
JPG
The usual format of a phone photo. Compression blurs thin lines a little, so take the photo close, in even light, with the whole sheet and its 4 corners in the frame.
DWG
AutoCAD's own format, written as DWG R2000 so that any AutoCAD since 2000 opens it. Drawings over 50,000 objects come as the DXF only, with a note: open it and save it as DWG in your software.
DXF
Autodesk's open exchange format. We write DXF R2000, which AutoCAD, BricsCAD, DraftSight, LibreCAD, QCAD, FreeCAD and QGIS open. Each colour and type of object gets its own layer.

FAQ

What does an AI blueprint reader do?

It reads what is written on a plan the way a person would: here, the title block's fields (project, sheet, title, scale, date, revision, author), turned into data you can paste into a register or a spreadsheet.

Which files can the blueprint reader open?

A PDF exported from CAD, a scanned PDF, a PNG, JPG or TIFF scan or photo, and DWG or DXF drawings. One sheet per file: for a PDF, pick the page on the preview.

Is the title block read accurately?

Clear printed text is read well, and every field is shown for you to check and correct before anything is exported. A field it cannot read stays empty rather than guessed.

Can I read the title block for free?

Yes: Max AI runs for free, once per file and 3 drawings a day, and the whole sheet shows on the page. The export with the CSV, the JSON and the drawing is $10.

What happens to my files?

Your files are deleted after 24 hours and never used for AI training. They are only used to make your conversion.

Who owns the converted drawing?

You do. You keep the ownership of your file and of the DXF and DWG made from it, commercial use included.

Do I need an account?

No. Drop a file, check the preview, download. The job page keeps your result for 24 hours.

What is in the download?

A zip with a DXF and a DWG (both R2000); a vector PDF from the DWG and DXF to PDF pages. Drawings over 50,000 objects come as the DXF only, with a note: save it as DWG in your software.

Is the drawing to scale?

Without a scale, a PDF comes in millimetres of paper and an image in pixels. On the preview, type the scale (1:100) or click two points and give the real distance between them.

Does it make 3D or BIM models?

No: you get a 2D drawing, lines, arcs, circles, fills and texts on layers. No 3D, no walls or rooms as BIM objects.

Are there limits on free conversions?

Free in every mode: 5 files and 3 downloads a day per visitor, files up to 50 MB, one PDF page per file. The counters reset at midnight UTC. Every example's DXF is free too.

What if the file doesn't open?
