Manufacturing Support

Sheet Metal Design & Fabrication Drawing Services

Sheet metal parts, weldments and fabricated assemblies designed and detailed for the shop that will make them — flat patterns and DXFs that match your press brake, weld symbols to AWS or ISO, cut lists, hardware callouts and BOM-complete fabrication drawing packages. Delivered native in your CAD, to your standard.

Service Overview

Drawings A Fabricator Can Build From Without A Phone Call

Fabrication drawings fail in predictable ways: flat patterns that do not match the bend allowance of the real press brake, weld symbols that leave the welder guessing, hardware with no PEM or rivet-nut specification, and assembly drawings with no sequence. We detail for the shop floor — the laser programmer, the brake operator, the welder and the fitter — and we ask for your bend tables, hardware preferences and welding process before the first part is unfolded.

The same team designs the parts, so when a flange will not clear a bend or a weld is unreachable, it is fixed in the model rather than discovered on the floor. Our fabrication work includes gearbox housings, machine frames, guards, enclosures and structural guides, each delivered as a complete package.

  • Sheet metal part design with flat patterns, bend tables or K-factors you specify
  • Weldment and frame design with structural profiles, cut lists and weld callouts
  • Fabrication drawing packages: part, weldment, sub-assembly and GA drawings with BOMs
  • DXF/DWG for laser, plasma, waterjet and punch, with or without bend lines, etch and bend marks
  • Hardware integration: PEM, rivet nuts, inserts, hinges, latches and gaskets
  • Enclosures, guards, chutes, hoppers, cabinets, brackets and machine frames

What this service is not: We do not provide CNC nesting or press-brake programming files beyond DXFs; those stay with your shop's software and operators.

What's Included

Sheet Metal & Fabrication Capabilities

Sheet Metal Part Design

Bends, reliefs, hems, louvres, embosses and formed features designed to your material, thickness, tooling and minimum flange rules.

Flat Patterns & DXFs

Unfolded to your bend table or K-factor; DXF exported with bend lines, etch marks and part numbers as your laser programmer needs.

Weldments & Frames

Structural profiles, gussets and plates with cut lists, weld symbols and sequence notes for frames, skids and bases.

Fabrication Drawing Packages

Part, weldment and GA drawings with BOMs, balloons, hardware callouts and finish specifications.

Enclosures & Guards

Electrical and equipment enclosures, machine guards and cabinets with doors, hinges, latches, gaskets and ventilation.

DFM For Fabrication

Review of existing designs for bend feasibility, weld access, tolerance stack-up across bends and cost drivers.

What We Need From You

Inputs We Work From

Send whatever you have. We list anything missing or ambiguous in a query sheet and agree it with you before modelling starts — nothing is assumed silently.

  • Sketches, concept models, existing drawings or a sample part
  • Material, thickness and finish; your bend table, K-factor or press-brake tooling data
  • Welding process and your preferred weld symbol standard (AWS A2.4 or ISO 2553)
  • Hardware preferences: PEM, rivet-nut, hinge and latch catalogues
  • Drawing template, title block and DXF conventions (layers for cut, bend, etch)
  • Target CAD platform and version

What You Receive

Deliverables & File Formats

Models

  • Native sheet metal and weldment models (SolidWorks, Inventor, Creo, Solid Edge, NX)
  • Configurations for material and thickness variants
  • STEP/Parasolid for suppliers on other platforms

Shop files

  • Flat-pattern DXF/DWG per part, bend lines and etch on your layers
  • Cut lists for profiles and plates; bend tables on drawings
  • Weldment drawings with weld symbols, sizes and sequence notes

Package

  • Fabrication drawing set: part, weldment, sub-assembly and GA with BOMs
  • Hardware and finish callouts; mass and paint-area where needed
  • Check record against inputs and standards

Native files in your platform and version (older versions on request), plus neutral STEP AP214/AP242, IGES, Parasolid, DXF and PDF as needed.

Standards & Platforms

Drawn To Your Standard, Delivered In Your CAD

We work to the drawing and design standards your market specifies. Editions below are current as of October 2026.

Standards we apply

  • AWS A2.4:2020 — Weld symbols for North American fabrication drawings
  • ISO 2553:2019 — Weld symbols for ISO-market (EU, UK, Australia, India) drawings
  • ASME Y14.5-2018 (R2024) / ISO GPS — Tolerancing, including tolerance stack-ups across bends
  • BS 8888:2025 / AS 1100 — Drawing presentation for UK and Australian fabricators
  • AS/NZS 5131:2016 (Amd 1:2020) — Fabrication and erection documentation conventions for Australian structural work
  • Your bend tables and DXF layer standard — Applied so flat patterns and cut files match your shop without rework

Native CAD platforms

You receive editable native files, not just exports. We do not advertise platforms we cannot deliver natively.

How The Work Runs

Our Process For This Service

1

Shop data first

We collect your material, bend and hardware rules so the model matches your process from the start.

2

Design and unfold

Parts and weldments are modelled, unfolded to your bend data and checked for bend feasibility and weld access.

3

Detail and DXF

Fabrication drawings, cut lists and DXFs are produced on your template and layer standard.

4

Check and deliver

A second engineer checks flat patterns, symbols and BOMs against the inputs; files delivered native plus DXF/PDF.

Worked Example

Fabricated Gearbox Housing Design

A fabricated gearbox housing designed as a weldment with sheet and plate parts — flat patterns to the client's bend data, weld symbols, machining allowances for bearing bores after welding, and a fabrication drawing package with cut list and BOM in SolidWorks and AutoCAD.

Engagement Models

Three Ways To Work With Us

Every quote states scope, deliverables, formats, standard, revision rounds and deadline. Prices are quoted per project — in USD, EUR, GBP, AUD or INR.

01

Fixed price per job

Best for defined scopes — a drawing set, a conversion batch, one analysis. You know the total before work starts.

02

Hourly with a cap

For evolving design work where scope is still forming. Hours are logged, reported weekly and never exceed the agreed cap without your sign-off.

03

Dedicated engineer

A named engineer reserved for your work, month by month, on your templates and in your CAD — an extension of your own design office.

Confidentiality & IP

Your Designs Stay Yours

NDA before files

We sign your NDA, or send ours, before a single drawing is shared.

IP assigned to you

Models, drawings and calculations are your property on payment. We keep no rights.

Named engineer

Only the engineers on your job can open your files. You deal with them directly.

Deleted on request

Project data is removed from our systems when you ask, with written confirmation.

Technical FAQ

Questions Engineers Ask Us

Which K-factor or bend allowance do you use?
Yours. We model with your bend table or K-factor per material and thickness so flat patterns match your press brake. If you have none, we agree values with you and record them on the drawing.
How are DXFs delivered for the laser?
One DXF per part at 1:1, with cut, bend and etch geometry on the layers you specify, part number and quantity in the file name, and optionally bend lines included or excluded as your programmer prefers.
Do you use AWS or ISO weld symbols?
Whichever your fabricator reads. AWS A2.4 for North American shops, ISO 2553 for ISO markets; we state the standard on the drawing.
Can you detail a frame for welding and then machining?
Yes. Weldment drawings carry the as-welded dimensions and a separate machining drawing carries post-weld machining with allowances, so bores and faces come out true.
Do you design enclosures to an ingress rating?
We design gasket grooves, door overlaps and drainage features to support a target IP rating and note the gasket and hardware required; the rating is confirmed by your testing.
Can you review an existing design for fabrication cost?
Yes. A DFM review lists bend feasibility, weld access, part consolidation and tolerance issues with recommended changes and the cost or quality reason for each.
Do you also do structural steel detailing?
Yes, as a separate service for steel structures: see structural steel detailing. This page covers machine, equipment and enclosure fabrication.
