ASME Y14.5 vs ISO GPS: Key Differences
ASME Y14.5 and ISO GPS drawings look alike but mean different things: envelope vs independency, projection, general tolerances and units.

Learn moreStructural Steel Detailing
Shop and erection drawings for platforms, frames, supports and plant steel.
Learn more3D Printing & Prototyping
In-house FDM and resin printing of prototypes, fixtures and functional parts.
Learn moreAutomation
Software that removes repetitive CAD and engineering admin.Case studies
Work we have delivered, with the drawings to prove it
Every case study states the brief, the inputs, the deliverables and the standards. Client names appear with permission; otherwise the sector is given and the name withheld under NDA.
High-Speed E-Motor and Motion Test Rig
A 138-part test rig for a high-speed electric motor — stator stack, samarium-cobalt magnets, Inconel rotor sleeve, front and rear end frames — mounted on adjustable alignment bases with couplings, blast case and guide rods, delivered as a SolidWorks assembly with 26 drawings on the client template.
Spiral Bevel Gearbox Design
3D CAD design of a right-angle spiral bevel gearbox — splined shafts, deep-groove ball bearings and a cast housing, proven in a full sectional view.
Subsea Insulation Covers and Moulding Tooling in Inventor
Subsea flowline insulation shrouds and an insulation cover designed in Autodesk Inventor for an offshore systems manufacturer — 38 assemblies and 277 parts covering inner and outer pipe pups, weld preparations, coating layers and the two-part moulding tools (base plate and core, cavity, fill plate, inserts, vent plate) on A1 drawings.
Textile Stenter: Chambers, Mangle and Overfeed Sections
Engineering models and drawings for a textile stenter — 5- and 8-chamber heat-setting sections, entry and exit frames, mangle with trough lift and pressure rolls, and the overfeed feeding assembly — built in Solid Edge for a textile machinery OEM.
25 kW Two-Stage Helical Gearbox with Twin Outputs
A 25 kW, 1750 rpm two-stage helical gearbox (ratio 6.33) with left- and right-hand 40T output gears, a fabricated housing with top cover and acrylic inspection window, 36-item BOM and 24 part drawings.
Sheet-Metal Ductwork Package from a European Customer's Drawings
Two dust-extraction ductwork assemblies — cyclone body, transition and hopper cone — modelled in SolidWorks from a European customer's French-language 2D drawings, then issued as 21 part drawings with flat patterns and thickness-sorted DXF files for a Gujarat sheet-metal shop.
Why manufacturers keep sending us work
Outsourcing fails on unclear inputs, unchecked outputs and surprise invoices. We removed all three.
Our process is built around the complaints engineers have about offshore drafting: silent assumptions, files that do not open, drawings nobody checked. Every job runs the same way, whether it is one drawing or a complete machine.
How we workQuery sheet first
Missing dimensions, materials and contradictions are listed and agreed before modelling starts.
Second-engineer check
Every package is checked against your inputs and standard; the check record ships with the files.
Native, your version
Files open and rebuild in your CAD with your templates, properties and PDM structure.
NDA and IP in writing
NDA before files; deliverables and IP are yours on payment; controlled access to your data.
Itemised quotes
Scope, deliverables, formats, standard and date on every quote, in USD, GBP, EUR, AUD, CAD or INR.
One named engineer
You talk to the engineer doing the work; product knowledge builds and briefs get shorter.

Global clients
Working across time zones is the point, not a problem
Work sent at the end of your day is on our desks at the start of ours. UK and European mornings overlap our afternoon; Australia overlaps our morning; US teams get overnight turnaround and early-morning calls.
- Drawing standard, units and projection matched to your market
- Quotes and invoices in your currency, paid by bank transfer
- Export-control and NDA questions settled before any file is sent
Automation
The tools that keep our own drawing office consistent, available to yours
Drawing creation, DXF export, nesting, PDF and document automation built in-house and used daily on client work.
CAD Automation
Drawings, exports, conversions and title-block changes done automatically across a whole project, with every result checked.
See the toolsProcess Automation
The repetitive work around engineering — registers, trackers, reports, PDFs and spreadsheets — handled by tools that read your documents and fill your templates.
See the toolsCustom Automation
When no off-the-shelf product fits, we design and build one — desktop application, engineering calculator or AI-assisted workflow — around your standards, templates and naming rules.
