End-to-end mechanical design engineering and CAD outsourcing for startups, manufacturers, product developers and engineering teams in India, the USA, UK, Europe and Australia. Each service ends in files, not opinions: a model you can open, a drawing you can print, and a format your supplier already works with.
Getting from an idea to a design that will work.
Concept development and product design engineering — from idea to a practical, manufacturable concept.
Mechanical product design and product development engineering — complete products designed to work and to be built.
Machine design services, special purpose machine (SPM) design and jig and fixture design built around your process.
Assemblies where the parts actually fit together.
The files and paperwork a shop builds from.
3D CAD modelling services — precise parametric solid models and assemblies in SolidWorks, Creo, CATIA V5, NX, Inventor, Fusion 360 or ZW3D.
Mechanical drafting and manufacturing drawing services — production drawings with nothing left to interpretation.
Sheet metal design services — formed parts that come out the size you intended.
Drawings and documentation in the language your supplier reads.
Engineering documentation services — the paperwork that turns a design into a repeatable build.
Making existing designs better, and covering your team when it is stretched.
Design for manufacturing (DFM) and optimisation — a second pass over an existing design to make it better and cheaper.
Reverse engineering CAD services — a physical sample, 3D scan or old drawing turned into a clean CAD model.
Help across the gap between a finished design and a made part.
Mechanical design outsourcing and contract engineering — an extra engineering resource when your team is at capacity.
Move through every stage with precision, efficiency and engineering confidence — or join at the stage where you need help.
The idea explored as an engineering problem, with alternatives compared.
A direction chosen on function, performance and manufacturability.
Precise parametric models of components and assemblies.
Dimensions, tolerances, GD&T, materials and bills of materials.
Print-ready files and support through the first build.
Revisions, manufacturing support and released documentation.
If your question isn't here, send it over — the answer usually takes one line.
Whatever exists: a sketch, a photo of the part next to a tape measure, an old print, or a written brief. If key dimensions are missing, we list the ones we need before quoting.
STEP and IGES for models, DXF and DWG for cutting and drafting, PDF for issued drawings, STL for printing. Native SolidWorks, Creo, CATIA V5, NX, Inventor, Fusion 360 or ZW3D files are available on request.
SolidWorks, AutoCAD, Fusion 360, Creo, CATIA V5, UG NX, Autodesk Inventor and ZW3D. We are CAD-software independent: work is done in the platform your team already uses, and CAD file conversion between platforms is included when needed.
Yes. RokOn Nexus is a mechanical design outsourcing partner based in Pune, India, working remotely with clients in the USA, UK, Canada, Australia, Germany and the rest of Europe. Files are exchanged securely, reviews are held over video call, and drawings can be issued in your supplier's language.
Yes. Technical drawings and engineering documentation can be issued in English, French, German, Chinese, Norwegian and Gulf Arabic, with other languages on request — useful when the shop building the part is not in the same country as the client.
Yes. Drawings are produced to ASME Y14.5 or ISO 1101 for GD&T, with ISO 2768 general tolerances unless your own drawing standard applies.
Yes. Support ranges from a single component to complete product development, including freelance and contract cover when your own team is at capacity.
Two review rounds are included in every quote. Each issued drawing carries a revision block, so the shop always knows which sheet is current.
You do. All models, drawings and source files are handed over on final payment, and we sign an NDA before receiving your files if you need one.
Describe the part and the problem. We'll tell you what the deliverable should be and what it costs.
