Remote reverse engineering / Worldwide

Reverse engineering.
STL scan to STEP CAD.

Reconstruct useful CAD geometry from an existing 3D scan. Share your STL and the dimensions that matter; we agree on the required result and deliver STEP files digitally.

Project details

A model built around your task.

A scan captures the existing shape. CAD reconstruction gives you geometry to continue designing, adapt a component or prepare the next manufacturing step. The brief determines which features must follow the scan and which need correction.

What to send

Send the STL file or a link, its units and at least one reference dimension. Include photos if the part is worn, broken or incomplete. Mark mounting faces, holes and any dimensions that affect fit.

Tell us the intended use, the STEP result you need and any dimensional requirements. If the scan contains gaps or noise, we first assess whether the available geometry and your measurements are sufficient.

What you receive

The agreed CAD reconstruction is supplied in STEP format. A triangulated STL mesh and a reconstructed CAD model describe geometry differently; this work involves rebuilding the relevant features, not simply changing the file extension.

STEP does not by itself promise a native feature tree. Drawings, additional formats, reports and other deliverables should be discussed before the project is agreed.

Dimensions, wear and verification

Identify the surfaces and dimensions that matter for your application. We agree on reference measurements and checks before reconstruction, including how worn or missing areas should be interpreted.

A scan alone cannot establish the original shape of an absent feature or prove physical fit. Supply mating-part information and measurements where needed; prototype or physical fit checks must be agreed separately.

Cost and timing

Assessment considers geometry complexity, scan quality, missing features, dimensional requirements and the agreed checks. Delivery timing and any revisions are discussed with the project scope.

If confidentiality needs to be addressed before sharing a file, send a general description first and ask to agree the arrangements. Do not include sensitive files in the first message.

How your project works

  1. Share the source

    Send the STL, scale, photos and intended use.

  2. Agree the result

    Confirm the features, reference dimensions, STEP deliverable and checks.

  3. Reconstruct and review

    Rebuild the agreed geometry and review it against the project requirements.

  4. Receive your files

    Receive the agreed STEP files digitally for your next engineering step.

Existing project / digital geometry

From a noisy scan to reconstructed geometry.

This coffee machine component was reconstructed from a noisy 3D scan. The existing project images show the source scan, rebuilt CAD and a deviation map. Accuracy requirements are agreed for each new project.

Questions before you start

Can we work together remotely?

Yes. Our studio is in Varna, Bulgaria; an existing STL scan can be assessed and reconstructed remotely, with STEP files delivered digitally.

I only have a physical part. What should I do?

Start with photos and dimensions. We can discuss scan requirements for a local scanning provider. Sending a physical sample from outside the EU is assessed individually before shipment.

Can a damaged or poor-quality scan be used?

Sometimes, depending on the usable geometry and the additional measurements available. Send images and describe missing areas so feasibility can be assessed before work starts.

Does the STEP file guarantee a printed part will fit?

Fit depends on the source data, agreed dimensions, material and manufacturing process. Physical fit and manufacturing checks must be part of the agreed project if you need them.
