Services

What we do

Anything from a single spare part to a complete product ready for series production.

3D model from sketch, drawing or photo

We interpret hand sketches, old paper drawings, photos with measurements and physical samples.

Model repair and modification

We fix broken STL files, convert meshes to STEP and rebuild models with a proper feature history.

Design for manufacturing

3D printing, CNC milling and turning, sheet metal, photo etching and injection moulding – right first time.

Technical drawings

2D drawings with views, sections, tolerances, threads and surface finish. PDF, DXF and DWG.

Manufacturability review

We check wall thickness, draft angles, radii and tolerances before you order parts.

Renderings and images

Photorealistic images for web shops, presentations, crowdfunding or patent applications.

Assemblies

Multiple parts that fit together: interference checks, fits and a bill of materials.

Confidentiality and NDA

Your ideas stay with us. We sign an NDA before opening your files.

Applications

Industries and typical projects

CAD design adds most value where a part has no drawing, needs improving or has to be made in a new way.

A01

Spare parts without drawings

Discontinued plastic parts, gears and brackets are measured and remodelled – often stronger than the original.

A02

Electronics enclosures

Enclosures for circuit boards with screw bosses, cable entries, ventilation and sealing for the chosen IP rating.

A03

Product development and prototypes

From idea and sketch to functional prototype, DFM review and data for a pre-production run.

A04

Jigs and fixtures

Drill jigs plus welding, gluing and inspection fixtures using the 3-2-1 principle – printed or machined.

A05

Machine and agricultural parts

Gears, shafts, bushings and brackets with fits to ISO 286 – for industry, forestry and agriculture.

A06

Vehicles and classic cars

Interior details, controls, clips and brackets for classic cars, mopeds and boats – in materials that withstand heat and UV.

A07

Sheet metal and photo etching

Bent and laser cut sheet metal parts plus photo-etched parts – with correct bend radii and DXF flat patterns.

A08

Design for injection moulding

Plastic parts with uniform wall thickness, draft angles, ribs and snap fits – ready for the toolmaker.

A09

STL to STEP and model repair

We turn STL, OBJ and 3MF into editable STEP models and repair broken meshes for printing.

A10

Reverse engineering

Measuring and CAD reconstruction of existing parts – from a sample, photos or a 3D scan.

A11

Technical drawings

Technical drawings to ISO with views, sections, tolerances, fits, threads and surface finish – for workshops and quotes.

A12

Inventors and patents

3D models, functional prototypes and line drawings for inventors – with an NDA before we start.

A13

Furniture and interiors

Furniture fittings, replacement furniture parts and drawings for CNC in wood – designed with wood movement in mind.

A14

Sports and outdoor

Mounts, adapters and accessories for bikes, skis, hunting, fishing and camping – in materials made for a Nordic climate.

A15

Design for 3D printing

Parts designed for FDM: no supports, the right clearances and walls, inserts for threads and an orientation that gives strength.

How it works

From enquiry to finished files

A clear process without surprises: you know the cost before we start modelling.

EnquirySend a sketch, drawing, photos, measurements or an existing file – and tell us what the part has to do.
Free reviewWe go through your material, ask any follow-up questions and estimate the hours.
Quote & approvalYou get a fixed price or a capped number of hours. No work starts until you approve.
DesignA parametric 3D model with full history, tailored to the chosen manufacturing method.
Review & changesYou receive images and a preview. Adjustments within the quote are included.
File deliverySTEP, STL, DXF, PDF drawings and renderings – whatever you need for production.

Why NordiTeq

Designed by people who also manufacture

Manufacturing know-how

We make parts ourselves and know what works in the real world – not just on screen.

Parametric models

Full history with dimensions and constraints makes later changes easy.

Clear pricing

Free assessment and a fixed price or capped hours before work starts.

Nordic and personal

Swedish VAT-registered company, communication in your language.

CAD services for Sweden, the Nordics and Europe

NordiTeq CAD helps companies, workshops, inventors and private customers with remote CAD design and 3D modelling. You send your material digitally and get finished files back – whether you are in London, Manchester, Dublin, Stockholm, Oslo, Copenhagen or anywhere else in Europe.

Typical projects are spare parts you can no longer buy, new products to be prototyped and then series-produced, fixtures that speed up production and old paper drawings that need to become modern 3D models. We design with the manufacturing method in mind. That means uniform walls for injection moulding, the right bend radii for sheet metal, accessible pockets for CNC milling and self-supporting geometry for 3D printing.

You get files that work with any supplier: STEP for CAD and CNC, STL and 3MF for 3D printing, DXF for laser and waterjet cutting, and PDF drawings with tolerances. If you are unsure which format you need, we explain the differences in the guide STEP vs STL. If you also need the parts made, NordiTeq 3D prints them and helps you on to CNC, sheet metal and injection moulding.

Behind NordiTeq CAD is a designer who also makes what is designed. Read more about us and how we work, or look up a term in our CAD glossary.

FAQ

What do you need to create a 3D model?

Photos from several angles and a few key dimensions are often enough. A sketch, an old drawing or a physical sample also works. The more precise the input, the faster and cheaper the job.

Which file formats do you deliver?

STEP and IGES for CAD and CNC, STL and 3MF for 3D printing, DXF and DWG for laser, waterjet and sheet metal, plus PDF drawings. Native files on request.

How much does CAD design cost?

It depends on the complexity of the part and the input material. You always get a free assessment and a fixed price or capped hours before we start.

How long does it take?

A simple part is often ready within a few working days. Larger products are planned in stages with clear deliverables.

Do you sign non-disclosure agreements (NDA)?

Yes. We are happy to sign an NDA before you send anything, and your files are used only for your project.

Can you convert an STL file to STEP?

Yes. We rebuild the mesh as a true solid model with planar faces, cylinders and dimensions – so it can be edited and machined.
