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:
| Country | Standards and codes we draft 3D CAD design services to |
|---|---|
| USA | ASME Y14.5 tolerancing on supplier drawings; UL or FCC requirements are handled by your compliance partner |
| UK | BS 8888 / ISO GPS drawings; UKCA marking requirements handled by your compliance partner |
| Canada | ASME/CSA drawing practice for North American suppliers |
| Australia | AS 1100.201 drawings and ISO GPS tolerancing |
How our 3D CAD design services process works
- 1Send 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.
- 2Fixed 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.
- 3Drafting & modeling
Your project is drawn in AutoCAD, Revit, Civil 3D, SolidWorks or the software you use, on your title block, layers and templates.
- 4QA check
A second drafter checks dimensions, annotations, layer standards, sheet numbering and cross-references against your input before anything is sent.
- 5Delivery & 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.
