Convert an OBJ model into manufacturing-ready CAD.
An OBJ carries the outside of a product. It does not carry wall thickness, draft, mounting bosses, tolerances, or the space your PCB actually needs. We turn the model you have into CAD a factory can build from — and stay on the project until parts are delivered.
What you send us
The OBJ file from your exterior design software — the one your industrial designer or design studio produced. It does not need to be tidy, and it does not need to be watertight.
The parts that must fit inside. The PCB, battery, connectors, speaker, sensors — whatever has to live in there. STEP files are ideal; dimensions, drawings or photographs are often enough to begin.
Anything already fixed. Overall size, material, IP rating, target cost, the production process you have in mind. The earlier we know these, the fewer revisions later.
What we return
Detailed 3D CAD of the enclosure and the internal architecture — rebuilt as real solid geometry, not a mesh with a new extension.
Manufacturing drawings with tolerances, so a toolmaker knows what is critical and what has room to move.
An assembly-ready structure. Parts that go together in a sensible order, with the clips, bosses and locating features that make it happen on a production line rather than on a bench.
Files your supplier can tool from. STEP, native CAD and PDF drawings — whatever the factory you choose asks for.
What we check before it leaves
Seven things decide whether a design can actually be moulded and assembled. Every one of them is resolved before the model goes out.
- 01Wall thicknessThick enough to mould and to carry load, thin enough to cool without sinking.
- 02Draft angleEvery vertical face needs somewhere to go, or the part will not release from the tool.
- 03Mounting points and bossesWhere screws go, how the boss is ribbed so it does not pull a sink mark on the visible face.
- 04Interfaces and cutoutsUSB, buttons, vents, light pipes — sized so the part still assembles after moulding tolerance.
- 05Tolerances and fitsWhich dimensions are critical, which can drift, and what the stack-up does when everything drifts at once.
- 06Component clearancesRoom for the tallest component, the connector that has to plug in, and the cable that has to bend.
- 07Assembly orderThe sequence a person on the line will actually follow, and whether the part can be reopened for service.
Who this is for
Hardware teams with a design model and no production CAD. You have something that looks right and needs to become something that can be made.
Companies whose design studio delivered a model that cannot be moulded as drawn. It happens constantly, and it is not a criticism of the designer — the brief was appearance, not tooling.
Teams reworking the internals around a new PCB. The shell stays, the inside has to change — a revised board, a bigger battery, a connector that moved.
We develop our own connected IoT products across enclosure, electronics and software. That is why the engineering judgement applied to your model comes from a team that ships its own.
Common questions
-
What is the difference between an OBJ file and CAD?
An OBJ is a mesh: a surface built from triangles. It describes the outside of a shape and nothing else — no wall thickness, no draft, no solid volume, no dimensions. CAD is a solid model with real geometry a toolmaker can work from. Converting between them is not a file-format change; it is a design job, because the decisions that make a part mouldable have to be made rather than translated.
-
What do you need from me to start?
The OBJ or mesh from your industrial design software, the internal parts that must fit inside it — the PCB, battery, connectors, speaker or sensors — and anything already fixed, such as overall size, material, IP rating or target cost. STEP files of the internal components are ideal, but dimensions and photographs are often enough to begin.
-
Can you work from a mesh that was never meant for manufacture?
Yes, and that is the usual case. Models from exterior design software are made to look right, not to be moulded. We rebuild the geometry as a solid, then resolve the details that decide whether it can actually be produced: wall thickness, draft angle, mounting bosses, interfaces, tolerances and component clearances.
-
Do you only deliver CAD, or do you handle production?
Both. The CAD and manufacturing drawings are the deliverable you can take to any supplier. We also carry the project through to production delivery, working with the manufacturing supply chain across the Guangdong–Hong Kong–Macao Greater Bay Area, so the distance between a finished model and a produced part stays short.
-
How long does a conversion take, and what does it cost?
It depends on the model and how much of the internal architecture has to be reworked — a clean model with a settled PCB is a very different job from one that needs the layout rebuilt around new components. Send us the model and we will come back with a realistic schedule and a fixed quote rather than a range.
-
How is confidential design data handled?
Customer models and design data are treated as confidential and handled under a non-disclosure agreement on request. Tell us before you send files if you need one in place first, and we will put it there.
Send the model. We will tell you what it needs.
Attach the OBJ and whatever you have on the internals. You will get a straight read on what has to change, a schedule and a fixed quote.
