Live teamwork
Everyone in a project sees edits within a fraction of a second. Comments pinned to the drawing, @mentions, assignments, tasks with attachments.
Wire harness design software
Design the harness once.
Build it right the first time.
Schematic, harness layout and 1:1 formboard share one live model, so a change in one is a change everywhere. Bills of materials, cut lists, build instructions and test programs are generated as you draw, for your whole team, on your own private server.
- Runs in the browser, nothing to install
- Live multi-user editing
- Imports Arcadia .hrx and Excel
One modelSchematic, layout and formboard never need syncing
Real lengthsEvery wire routed through the bundles, with cut allowances and tolerances

Design
From the first pin to the released drawing
Schematics that know the harness
Multi-sheet schematics with signal names and click-to-wire. Every connector shows whether its wires are routed. Devices such as ECUs, relays, fuses, switches and lamps come with their pins.
- Simulate switches, relays and fuses: live wires glow, loads light up
- Electrical checks: voltage drop, ampacity with bundle derating, fuse coordination
- Cables, twisted pairs and shields, billed by length or twisted in-house
- Variants with option codes that filter drawings, BOM and reports
Layout and formboard at true scale
Draw bundle paths, drop connectors and splices on them, and every wire takes the shortest route. Lengths carry company tolerances, and coverings size themselves to the bundle.
- 1:1 formboard as SVG or DXF, or tiled onto A4/Letter pages with a check bar
- Underlays: trace over a vehicle or machine outline, DXF at true size
- Pin charts, detail views and your own drawing frames and title blocks
- Bend radius and fill checks on every bundle
Revisions and change orders
Draft → review → release, locked snapshots, revision compare with BOM deltas, ECOs with named approvers and printable change notices.
Company standards
Shared parts library, catalogues, design rule profiles (automotive, aerospace, industrial), cut-length rules, numbering patterns and revision schemes.
Bring your designs with you
Import Arcadia .hrx files, From-To lists from Excel or CSV, and supplier catalogues. Round-trip the wire list through Excel and review every change.
Customer portal
Share a project or a whole customer folder. Customers see released drawings and change notices, and approve or request changes.
Connects to your systems
REST API for BOMs, wires, cut lists, nets and checks; signed webhooks; Slack and Teams messages; single sign-on with Microsoft, Google or Okta.
Manufacturing
The shop floor gets what it needs, generated
No retyping into spreadsheets. Every output comes from the same design, and updates when it changes.
Bill of materialsTerminals, seals, plugs, coverings, labels and fixings filled in from the parts, with costs from your price list
Cut listOrdered by spec, gauge and colour, with strip lengths and your company cut rules
Crimp, splice and tool listsGrouped by crimp tool and terminal; splices with A/B sides and mm² per side
Splice weld settingsYour ultrasonic welder charts (EW-6030 preset), looked up from each splice's cross-section
Build instructionsStep by step: cut, crimp, splice, load connectors cavity by cavity, lay up, test
Test programPoint-to-point continuity and isolation, exported for your tester
Excel workbookUp to 14 sheets in one click, with report profiles per plant or customer
Drawing packagePDF with layout, BOM, schematics, connector charts and wire list, every sheet at paper size
"Is this print current?"A QR code on every sheet tells the floor whether that revision is still the release
Cost and weightUnit cost at any batch size with labour rates, and harness weight, per variant
Your server, your data
A private workspace for every company
Harness Forge isn't one big shared database. Each company gets its own dedicated server with its own database, storage and backups. Your designs are never mixed with another customer's.
Updates are rolled out for you, with an automatic backup before each one.
- Two-step sign-in with any authenticator app; require it for admins or everyone
- Single sign-on through Microsoft Entra ID, Google Workspace, Okta and others
- Roles: admins, engineers, viewers, and outside partners who see only what's shared
- Security log of sign-ins, failures, devices and changes, exportable
- Encrypted nightly backups, checked for integrity, restorable on request
- Hardened servers: HTTPS only, key-only admin access, intrusion blocking, automatic OS security updates
