Everything between the idea and the issued drawing

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.

3D CAD modelling

S-01

Parametric solid models of parts and assemblies, built to be edited later without breaking.

  • Part, assembly and configuration modelling
  • Design tables for size families and variants
  • Mating, interference and motion checks
  • Delivered as STEP, native CAD and STL

2D production drawings

S-02

Drawings a workshop can quote from and cut to, with nothing left to interpretation.

  • Fully dimensioned views, sections and details
  • GD&T to ASME Y14.5 or ISO 1101
  • Weld symbols, surface finish, BOM and revision blocks
  • Issued as PDF plus DWG or DXF

Sheet metal and fabrication

S-03

Formed parts developed with the right bend allowance, so the flat pattern comes back the size you expect.

  • K-factor and bend deduction development
  • Flat patterns and nesting-ready DXF
  • Enclosures, brackets, chutes, guarding, skids
  • Cut length and pierce count for laser, plasma and waterjet

Reverse engineering

S-04

A measured sample, a rusted spare or a faded print turned into a clean, dimensioned model.

  • Models from physical parts and hand measurements
  • Legacy paper and scanned drawings redrawn
  • Obsolete part replacement and fit checks
  • Tolerances recovered from function, not guesswork

Design for manufacturing

S-05

A second pass over the design to take out cost that the drawing was quietly adding.

  • Tolerance stack-up and fit analysis
  • Material, coating and process selection
  • Standard fastener and stock size rationalisation
  • Machining, casting and fabrication feedback

Prototyping and documentation

S-06

Everything needed to build the first one and then repeat it.

  • Print-ready files for FDM, SLA and SLS
  • Assembly instructions and exploded views
  • Drawing packs and revision control
  • Spare part and maintenance documentation
Engagement

How a job moves from enquiry to release

  1. 01

    Send what you have

    A sketch on paper, a photo with a scale next to it, an old drawing, or a full brief. Key dimensions and the mating parts are usually enough to start.

  2. 02

    Scope and quote

    You get the deliverable list, file formats, revision count and lead time in writing before any modelling begins. No open-ended hours.

  3. 03

    Design and review

    A model and draft drawing come back for comment. Changes are made against your markups until the design is signed off.

  4. 04

    Release files

    Final pack issued in the agreed formats, with a revision block that lets you track what changed and when.

Questions

The things clients ask first

If your question isn't here, send it over — the answer usually takes one line.

What do you need from me to start?

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.

Which file formats do you deliver?

STEP and IGES for models, DXF and DWG for cutting and drafting, PDF for issued drawings, STL for printing. Native SolidWorks or Fusion files are available on request.

Do you work to drawing standards?

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.

How are revisions handled?

Two review rounds are included in every quote. Each issued drawing carries a revision block, so the shop always knows which sheet is current.

Who owns the design?

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.

Not sure which service you need?

Describe the part and the problem. We'll tell you what the deliverable should be and what it costs.
