01 — Services

What you get

3D Modeling

SolidWorks parts and assemblies, from sketch to production-ready parametric model. Photorealistic Keyshot renders available for your product presentations.

Drawings & Documentation

ISO-standard manufacturing drawings, GD&T tolerancing, bills of materials — ready for your suppliers.

Tooling & Jigs

Machine tooling design, inspection jigs — my specialty, forged on the real production floor.

Optimization & Redesign

Reworking parts deemed "impossible to machine" — I know where to find the problem, and how to fix it.

Reverse Engineering

3D scan, point cloud or existing part → rebuilt into a usable STEP model for manufacturing or redesign.

Parts straight from the shop floor

From heavy industry to consumer products — events, cycling, motorized toys, vaping. Click a thumbnail to zoom.

Reverse engineering of a mechanical part: raw 3D scan mesh on the left, rebuilt surfaced STEP model on the right

Reverse engineering — 3D scan to surfaces

Raw scan mesh with torn edges and visible facets (left), rebuilt as continuous surfaces and closed into a STEP solid (right). Clean geometry, editable in CAD and ready for manufacturing.

Converting a triangulated STL mesh into a solid STEP model suitable for CNC machining

STL → STEP — mesh rebuilt as a solid

Client-supplied triangulated STL (left) rebuilt as a parametric solid (right): edges and fillets restored, a file the machinist can open and cut straight away.

03 — About

Why trust me with your drawing

A young company, but ten years of industrial experience that directly benefit your project — not a promise, a track record.

Years in the automotive industry

Design and production follow-up in real conditions, not just in a design office.

⚙

Rare dual expertise

I design AND I know how to machine. I spot upfront the drawings that will cause trouble on the shop floor.

⏱

Fast response guaranteed

No large design office: a single point of contact, replies within 24h.

My previous projects are often covered by industrial confidentiality — public reviews will build up with my next clients. You could be the first.

03b — Expertise

The micron when it matters, not as a habit

Tight tolerancing is expensive to manufacture. Knowing where it really matters — and where it doesn't — is what keeps a project on budget.

Dimension chains & functional clearances

I size parts for the clearance actually required, calculate dimension chains upfront, and only apply tight tolerances where it changes the assembly's behavior. Everything else stays at standard tolerance — and that shows directly on the machining quote.

Multi-trade supplier network

Machining, sheet metal, welding, boilermaking: I don't only talk to machinists. Depending on the part, I know how to point toward the right process and talk directly to the right fabricator — which avoids over-specifying a part that should simply have been bent or welded.

Materials & machinability

Grade selection based on the real application — mechanical properties, heat treatment, machinability, cost. A part nitrided to 700 HV doesn't have the same spec as a black-oxide part: I know that before drawing, not after the first machining trial.

3D Printing

Rapid prototyping, short-run parts or non-critical jigs — I use 3D printing as a complement to machining, to move fast when the part allows it and keep machining for what truly requires it.
