1 job a day freeSTEP + drawing

PMI Studio

Upload the STEP model and the customer drawing. An AI reads every requirement on the drawing and writes STEP AP242 with semantic PMI on the 3D model, ready for Mitutoyo MiCAT Planner to build the CMM program.

How it works

From drawing to AP242 in four steps

Upload STEP and drawing

The STEP model, ideally a native CAD export as one closed solid, and the drawing as PDF, vector or scanned. An intake check tests both before any AI runs.

The AI reads the drawing

It reads the drawing tile by tile and assigns every requirement to real faces and edges of the model. A job usually takes a few minutes, at most about 60, in the background.

Review

See every requirement next to its drawing crop and the 3D model, correct what is needed and collect the questions for your customer.

Export

The export writes and checks the STEP AP242 file. The delivery bundle holds the PMI STEP, the expected characteristic list and a pilot checklist for the MiCAT import.

What you get

Every inspectable requirement, on the model

Dimensions with limits

Dimensions as semantic PMI on faces and circular edges, each with limits: explicit, from the fit or from the general tolerance.

GD&T and datums

Geometric tolerances with their datums.

Questions instead of guesses

What is ambiguous is not guessed. It is held back and listed as a question for your customer.

Status from checks

Draft, content checked or Mitutoyo-ready. The status is computed from checks, never typed in.

What stays out, with a reason

Theoretically exact and reference dimensions, notes for another production stage and open questions are listed, not written as PMI.

Delivery bundle

PMI STEP, an optional simplified second file, the expected characteristic list and a pilot checklist.

Your data

PMI Studio is a tool by Imnoo. The drawing is read by an AI model to extract the requirements. You check every result in the review before you export it.

Questions

PMI Studio FAQ

What is PMI?
PMI (Product and Manufacturing Information) is the manufacturing and inspection information on the 3D model: dimensions with tolerances, geometric tolerances and datums. Semantic PMI in STEP AP242 is machine-readable, so measuring software such as Mitutoyo MiCAT Planner can create a CMM program from it.
Which files do I need?
The STEP model of the part and its drawing as PDF. Best is a native CAD export as one closed solid of the production stage being inspected. The intake check finds an invalid model before the job starts.
How reliable is the result?
An AI reader reads every tile; what is ambiguous is listed as a customer question instead of guessed. Draft means exported but not independently checked. Mitutoyo-ready applies only after checked content, a passed pilot import in the customer's MiCAT version and answered questions.
How long does a job take?
Usually a few minutes, up to 60 minutes. The job keeps running in the background, its page shows the progress, and the export follows automatically.
Is PMI Studio free?
You can try it for free: 1 new job a day without an account, 3 with a free Imnoo account and 30 with an Imnoo subscription.
