Drawing intelligence · tolerances · GD&T · should-cost
DocDFM is Partimation's drawing reader: upload a drawing and it pulls dimensions, tolerances, and GD&T straight off it — a clean CAD export, a scanned print, or a PDF that's been photocopied for twenty years — each value carrying its own confidence score, with no 3D model required. Read the print sitting in front of you, not the model you wish you had.

The problem
Datums, feature control frames, plus-or-minus calls — someone reads every one off the drawing just to build a quote. It's slow, and it's easy to miss one buried in a note.
A tight bore or a position callout changes the process, the stock, and the finish more than the part's geometry does — and it's easy to price the job before anyone's actually read the callout.
Scans, faxed prints, twenty-year-old legacy drawings — a real share of RFQs arrive as a 2D image with nothing behind it, so 3D tools sitting on your desk can't help at all.
What you get
Drop in a scan, a PDF, or a raster print — DocDFM reads it the way an estimator does, off the sheet itself, with no 3D model required anywhere in the process.
Dimensions, tolerances, and GD&T callouts come off the drawing with a confidence score attached, and anything uncertain gets flagged for a human to check before it's trusted.
Tight features drive machining stock, process choice, and finish more than shape does — Partimation prices them with the same engine that prices fabrication and casting work, so the number stays consistent across the shop.
Unit sanity, tolerance against your shop's real process capability, dimensions against the holes Partimation actually detects — the print gets checked against itself before the number goes out the door.
How it works
Upload a DXF, PDF, or CAD export — or just a scanned or photographed print. No 3D model needed.
Dimensions, tolerances, and GD&T come back tagged by source — vision, vector, or PMI — each with a confidence score.
The tightest callouts drive process, stock, and finish, and threaded callouts price straight through the same engine behind machining, fabrication, and casting work — add the 3D model and the full should-cost follows.
Unit sanity, tolerance-vs-capability, and dims-vs-holes get checked automatically, so errors surface before the quote goes out.
Pricing
Priced for a one-person shop reading prints off a scanner and a production job shop alike. Reading drawings is unmetered — run as many as you like.
EUR and GBP prices exclude VAT, added at checkout where it applies. Early adopters keep their price as the suite grows.
Run it your way
Sign in and read a drawing from any browser. We run the compute, ship the updates, and keep your data yours — the shared model only ever learns from your own drawings to calibrate its confidence.
Aerospace and anyone holding NDA drawings can run the whole thing on their own hardware. Licenses and updates are signed files — it never phones home, so an air-gapped install stays air-gapped.
Beyond reading tolerances off a single print, Partimation also builds the revision chain from a drawing's rev table, parses title block and BOM data, and — when a 3D model is also on file — checks the drawing's callouts against it. See the drawing-specific entry for the full detail.
FAQ
A scanned, PDF, or raster drawing on its own is enough to pull dimensions, tolerances, and GD&T off the sheet. No 3D model is required anywhere in that path. Every extracted value carries its own confidence score and the source it was read from, so the requirements you quote against come off the print in front of you rather than a model nobody sent.
Scanned, photographed, and raster prints go through the same reader as a clean CAD export. What differs is the confidence: every value comes back with a score for how well it was read, and anything below the threshold is flagged for a human to check. A twenty-year-old photocopy shows as a poor read on the screen rather than getting priced silently into the quote.
Every dimension, tolerance, and GD&T callout comes back with its own confidence score and the source it was read from — vision, vector, or model PMI. Vision means it came off a raster image, vector means it came from the drawing's own line data, PMI means it came off the model. Low-confidence reads are flagged for a human instead of being accepted into the numbers.
Tolerances tighter than the process can hold get flagged before the quote goes out. Two more cross-checks run in the same pass: unit sanity on the drawing's own numbers, and the drawing's dimensions against the holes actually detected in the model. The callout that doubles a price surfaces at review, while you can still ask the customer about it.
