Drawing → 3D model. Every dimension verified, every ambiguity — asked.

Send a PDF, scan or DXF — get STEP and STL, a video of the model and notes on the drawing. The video and notes are free; you pay only if the model fits.

What you can order

The system does the work under an engineer's control. During the pilot, some checks are done by a human.

Drawing→Model

3D model from a drawing

A part built from your drawing, with every dimension checked. We don't guess ambiguous spots — we ask, with ready answer options.

You provide
PDF, scan, photo, DXF or DWG
You get
STEP and STL, a video and catalogue images of the model, notes on the drawing; optionally a FreeCAD model with a feature tree
Turnaround
10 minutes to an hour, depending on complexity

Assembly from drawings

Each part of the assembly as its own model, and all of them together in an assembly model. We check that parts don't intersect.

You provide
assembly drawing and part drawings (PDF or ZIP)
You get
assembly STEP with named parts, a STEP per part, bill of materials, interference report
Turnaround
1–2 days: every part is additionally checked by a human
from$10$20per partDetails →Order

Drawing archive digitisation

A stack of paper or scanned drawings turned into 3D models. A status for every sheet: done, has a question, or needs a better scan.

You provide
multi-page PDF, scans or ZIP
You get
a model per sheet, a register with statuses, one combined list of questions
Turnaround
turnaround quoted upfront from the size of the batch
from$8$16per sheetDetails →Order

Flat pattern for laser cutting

The flat blank of a bent part, with bend allowance. A wrong allowance scraps the whole batch, so we verify every flat pattern by folding it back.

You provide
drawing or 3D of the bent part, thickness, material
You get
1:1 mm DXF outline for cutting, DXF with bend lines and bend table, 3D model
Turnaround
10 minutes to an hour, depending on complexity

What you get

Everything for your order on one page.

This is what your order page looks like. You see the price together with the model — before paying. The example is built from a public NIST drawing (heat sink 827-9999-904); the notes are illustrative.

  • Free before payment: the model video, the “drawing → model” check of every dimension, the model overlaid on your drawing, and notes. You pay only if the model fits.
  • The price is fixed per part class. We determine the class from the drawing and show it on the order page before payment.
  • Deviations from the drawing are fixed free of charge; so is your first change request.
  • Have a promo code? Enter it when ordering or on the order page.

Card payments for international clients are being connected. During the pilot, files are unlocked with a promo code: get one free in the box at the bottom of the page or email rodion@rodex.codes.

How we verify

A model reaches you only after every check has passed or been turned into a question.

Every dimension measured

Drawing dimensions are checked against the model by software, not by eye. A dimension doesn't match — the model doesn't ship.

Reverse shape check

We overlay the model's views and sections on the drawing: anything extra or missing shows up at once.

A second, independent checker

The finished model is checked from scratch by a separate agent that didn't build it. Mandatory on complex sheets.

Ambiguity becomes a question

If a drawing can be read two ways, you get a question with options, not a silent guess.

NIST heat sink drawing 827-9999-904
From a real run

A 6.35 mm error caught before delivery

A heat sink from the public NIST set: 59 dimensions. The builder read “2X .825” as the pitch between pin rows, but it is measured from the edge — the second row shifted by 6.35 mm. Every other dimension still matched.

The independent checker found the deviation, NIST's reference model confirmed it, and the model was fixed before delivery. That's why verification is a separate step for us, not a checkbox.

FAQ

How is the price calculated?

The price is fixed per part class: simple — up to 25 dimensions on the sheet, medium — 25–60, complex — over 60 dimensions, many views and sections, or castings. We determine the class from the drawing; you see it and the price on the order page together with the model video — before paying. Assembly — sum of the parts + 30 %, archive — per sheet by its class. 50 % pilot discount applies.

What if the model doesn't match the drawing?

If the model doesn't match your drawing, that's our mistake — we fix it free, as many times as needed. Changes you want that weren't on the drawing: the first is free, then at the price of the work. Tell us on the order page what's wrong.

What format is the model in?

STEP — opens in KOMPAS-3D, SolidWorks, Inventor, Fusion, FreeCAD; STL — for 3D printing. Optionally a FreeCAD model with a feature tree so you can change dimensions. We tested opening our STEP in KOMPAS-3D: dimensions and mass match.

Which drawings work?

PDFs, scans and photos of paper drawings, DXF and DWG, multi-page batches. Save KOMPAS files (.cdw) as PDF or DXF. If a sheet only has an isometric view without dimensions, we'll tell you honestly that an exact model can't be built from it.

Where do my files go?

Processing runs on the Claude model (Anthropic, USA). Our engineer receives the drawing (via Telegram). We never publish your drawings; order files are kept on the site for 180 days. If your drawings can't leave the country, tell us in advance.

Who is responsible for the result?

We are responsible for every dimension being verified and everything ambiguous being raised as a question or a note. Final acceptance is done by your engineer — everything needed for a quick check comes with the model.
