What our 3D CAD design service covers

3D CAD design is where an idea becomes something a supplier can quote. We take your sketch, reference product or written requirements and develop a parametric model that is easy to change: key dimensions are driven by a few parameters, parts are built in a logical order, and assemblies use proper mates so you can check movement and interference.

Design-for-manufacturing is part of the job. A machined part needs tool access and sensible radii; sheet metal needs bend reliefs and consistent thickness; a moulded part needs draft, uniform walls and ribs instead of thick sections; a 3D-printed part needs to respect the process's minimum features. We flag these early instead of discovering them when the first quote comes back.

This service is product design. For drawings of an existing design, see mechanical drafting; for machines and equipment, mechanical design services; for photorealistic marketing images, 3D product rendering.

Deliverables you receive

  • Parametric 3D part and assembly models
  • Design-for-manufacturing review notes
  • Interference and motion checks in the assembly
  • Prototype-ready files: STEP, STL for 3D printing
  • 2D drawings for suppliers with tolerances
  • Quick renders for internal review

What we need from you

  • Sketches, photos or a reference product
  • Functional requirements and key dimensions
  • Target manufacturing process and material
  • Quantity range (prototype, low volume, mass production)

Who orders this service

  • Start-ups and inventors
  • Product development teams with peak workloads
  • Small manufacturers without in-house CAD
  • Industrial designers who need engineering CAD

Software and file formats

SolidWorks and Autodesk Inventor native files, STEP, IGES and Parasolid for suppliers, STL/3MF for 3D printing, and PDF drawings. Fusion 360 files on request.

3D CAD Design Services standards in the USA, UK, Canada and Australia

We set up every project on the standard of the country where it will be built or manufactured. These are the references we work to most often:

CountryStandards and codes we draft 3D CAD design services to
USAASME Y14.5 tolerancing on supplier drawings; UL or FCC requirements are handled by your compliance partner
UKBS 8888 / ISO GPS drawings; UKCA marking requirements handled by your compliance partner
CanadaASME/CSA drawing practice for North American suppliers
AustraliaAS 1100.201 drawings and ISO GPS tolerancing

How our 3D CAD design services process works

  1. 1
    Send your files

    Upload sketches, PDFs, markups, photos, scans or a model through the quote form. Tell us the standard (US, UK, Canada or Australia) and the deadline.

  2. 2
    Fixed quote in hours

    We review the scope and reply with a fixed price, the deliverables list and a delivery date. Nothing starts until you approve it.

  3. 3
    Drafting & modeling

    Your project is drawn in AutoCAD, Revit, Civil 3D, SolidWorks or the software you use, on your title block, layers and templates.

  4. 4
    QA check

    A second drafter checks dimensions, annotations, layer standards, sheet numbering and cross-references against your input before anything is sent.

  5. 5
    Delivery & revisions

    You receive native files plus PDFs. Comments come back as markups and we revise them quickly until the set matches the brief.

Turnaround and pricing

Concept models usually take 2–4 business days; a full product with assemblies and drawings is planned in milestones over 1–4 weeks. Every job is priced as a fixed quote after we review your files, so you know the cost and the delivery date before work starts. See how our pricing works, or send your files through the quote form for a quick estimate.

3D CAD Design Services projects often need mechanical design services, mechanical drafting services and 3D product rendering as well. You can order them together on one quote, or browse every option in our design services.

Frequently asked questions

What is 3D CAD design?

3D CAD design is creating a product or part as a digital 3D model that defines its exact shape and size, so it can be checked, prototyped and manufactured.

Can you design a product from my sketch?

Yes. A sketch with the main dimensions and a description of how it should work is a normal starting point.

Do you sign an NDA for product ideas?

Yes. We sign your NDA before you share any design details.

Will I own the CAD files?

Yes. Once the project is paid, the models, drawings and design files belong to you.

Can you prepare files for 3D printing?

Yes. We export watertight STL or 3MF files and adjust walls and features to suit FDM, SLA or SLS printing.

We outsourced our 3D CAD design services to them for the first time and it was smooth from start to finish. Fixed quote in a few hours and files back before the deadline.

RRyan C.Interior designer · Alberta, Canada · 1 week ago
★★★★★

Very happy with the 3D CAD design services. They followed our standards, asked the right questions instead of guessing, and the QA was obvious – almost nothing to correct.

JJack F.Product designer · Brisbane, Australia · 3 weeks ago
★★★★★

Third project with them now. For 3D CAD design services they are faster than our in-house team and the native files open perfectly on our side.

MMichael P.Home builder · Florida, USA · 2 months ago
★★★★★

Needed 3D CAD design services urgently for a submission. They turned it around in 24 hours and kept us updated the whole time. Highly recommended.

SSophie B.Fabricator · Leeds, UK · 1 week ago
★★★★★

Clear pricing, clean drawings and quick revisions. Their 3D CAD design services saved us a lot of evenings this quarter.

DDaniel K.Homeowner · Ontario, Canada · 3 weeks ago
★★★★★

Good communication across time zones – we send markups at night and wake up to updated sheets. Solid 3D CAD design services at a fair price.
