3D CAD
DESIGN
From concept sketch to production-ready STL or STEP file. Our engineering design team handles 3D modelling, product design, industrial design and drafting for clients across Australia. Most projects deliver in 3–5 business days with revisions included until you approve the result.
What we design
3D Modelling

Product Design
End-to-end product design from brief to manufacture. DFM analysis, material selection and prototyping built in.
Industrial Design
Functional and aesthetic design for industrial and commercial products. Ergonomics, compliance and manufacturing constraints considered.
Technical Drafting
2D technical drawings, dimensioned shop drawings and assembly instructions from existing 3D models or physical parts.

How are 3D CAD design projects quoted?
Every design project is quoted individually based on scope. We work fixed-price, never hourly — you know the cost before we start.
What we look at to prepare a quote:
- Part complexity — single part vs multi-part assembly, surfacing requirements, tolerance specifications
- The source you provide — sketch, photo, sample part, scan data, or existing CAD in another format
- Output scope — CAD only, or CAD plus dimensioned drawings, plus assembly instructions, plus DFM review
- Industry & compliance — aerospace, medical and regulated industries may require additional documentation
- Revisions — included in every quote until you approve the result, not billed per round
Send us your brief on the contact page — sketches, photos and sample parts all welcome. We send a fixed-price written quote within 24 business hours. NDA available before any details are shared.
File formats we accept and deliver
We accept input in any common CAD or sketch format and deliver in your preferred output format(s). Multi-format export is included in every quote.
Accepted input
- STEP (.step, .stp), IGES (.iges, .igs)
- SolidWorks (.sldprt, .sldasm, .slddrw)
- Fusion 360 (.f3d), CATIA (.catpart)
- Sketches as PDF, JPG, PNG or hand-drawn photo
- Existing physical parts (we can scan in-house)
Output we deliver
- STL — for 3D printing
- STEP, IGES — for downstream CAD / CNC
- DXF — for laser / waterjet / sheet metal
- PDF — dimensioned drawings, AS/ISO compliant
- Native SolidWorks / Fusion 360 source files

STL, STEP, IGES, DXF, PDF — whatever your downstream process requires. Source files included.
3D CAD design disciplines, explained
“3D design” covers several distinct disciplines, and most real projects need more than one. Knowing which applies to your part helps us scope the work accurately and keeps the quote tight.
Parametric solid modelling
The backbone of most engineering work. Each feature (an extrude, a hole, a fillet) is driven by editable dimensions, so a single number change ripples through the whole model. This is what makes later revisions fast and keeps a family of similar parts consistent. Used for brackets, housings, enclosures, mechanical assemblies and anything destined for CNC or injection moulding.
Surface modelling
For organic, flowing or styled shapes that solid modelling handles awkwardly — consumer product shells, automotive trim, ergonomic grips. Surfacing controls curvature continuity so the finished part looks and feels right, then the surfaces are thickened into a solid for manufacture.
Assembly modelling
When parts have to fit together, we model them in an assembly with real mates and constraints. This catches interference and clearance problems on screen before any metal or plastic is cut, and produces an accurate bill of materials and exploded assembly drawings.
Design for additive manufacturing (DfAM)
If the end goal is a 3D print, the model should be designed for the process. We account for minimum wall thickness, overhang and support strategy, orientation for strength, and tolerance for the chosen technology (FDM, SLA, SLS or MJF) so the first print is usable rather than a test piece.
Which CAD software suits your project?
We work across the major CAD platforms and choose the right tool for the part rather than forcing every job through one package. The choice rarely matters to you — you receive neutral STEP, IGES or STL files either way — but it does affect how efficiently the work gets done.
- SolidWorks — our default for mechanical parts, assemblies and production drawings. Strongest for parametric engineering work that needs clean, dimensioned manufacturing documentation.
- Fusion 360 — well suited to product design, organic surfacing and projects heading straight to CAM or 3D printing. Good when modelling, simulation and toolpaths live in one place.
- CATIA — reserved for high-end surfacing and aerospace/automotive work with demanding Class-A surface or large-assembly requirements.
If you already work in a particular package and want native source files back, tell us in your brief and we will model in that platform.
3D CAD design — common questions
What do you need from me to start a design?
Whatever you have. A hand sketch, a photo of a sample part, a rough description, a competitor product, or an existing file in any format is enough to begin. The more detail on dimensions, materials and intended use you can give, the faster we converge on the right result.
How long does a 3D CAD design project take?
Most single parts deliver in three to five business days. Multi-part assemblies and projects needing surfacing, simulation or compliance documentation take longer, and we confirm the exact timeline in the written quote before starting.
Can you design a part so it can be 3D printed?
Yes. We design with the chosen manufacturing process in mind. For prints, that means correct wall thickness, support and orientation strategy, and tolerances matched to FDM, SLA, SLS or MJF. Because we run the printing in-house, the design and the print stay consistent.
Do you redesign or improve an existing product?
Often. We reverse engineer an existing part (from a sample or a 3D scan), rebuild it as an editable parametric model, and then make the changes you need — fixing a fit problem, reducing material, updating a feature, or preparing it for a different manufacturing process.
Who owns the design files?
You do. On completion the CAD files and all exported formats are yours, including the native source files on request. An NDA is available before any details are shared, and is included as standard.
