Wiring harness 3D CAD design
Full 3D harness models routed against your vehicle CAD — for packaging studies, clash detection, assembly drawings and a BOM you can trust.
Deliverables and scope
Each engagement is priced and scoped before we start — no scope creep, no surprises.
-
Routed 3D model
Branches routed against your vehicle or chassis CAD — accurate centre-lines, real connector geometry, real bend radii.
-
Clash + clearance report
Automated check against moving parts, heat sources, sharp edges and sealing surfaces. Findings written up, not just flagged.
-
Length-accurate BOM
Wire lengths and tape lengths driven by the model, not estimated. The BOM matches what the build shop will actually cut.
-
Assembly drawings
Flat-board layouts, branch labels, formboard pegs — exported in your build partner's preferred format.
From brief to sign-off
- 01
CAD handover
We take your vehicle CAD in any common format — STEP, JT, Catia, Creo, NX, SolidWorks — and stand the harness up against it.
- 02
Initial routing
First-pass 3D routing inside one week of CAD handover. You see the model in motion before the schematic is locked.
- 03
Clash + iteration
Routing iterates with packaging — moving parts, thermal zones, service access. Each iteration is a short loop, not a six-week silence.
- 04
Release
Final 3D model, length-accurate BOM, flat-board drawings, formboard data — released as one coherent pack.
Common questions
Which CAD packages do you route in?
Siemens Capital, Zuken E3.HarnessBuilder, Creo Schematics and NX Harness — plus our own platform. Talk to us about your stack and we will tell you straight how clean the integration will be.
Can you work from a 2D schematic we already own?
Yes. The most common starting point is exactly that — an existing schematic, a partial 3D CAD set, and a list of what changed in the latest vehicle revision. We pick it up and bring the 3D up to date.
Do you do digital-twin or simulation work?
We deliver length-accurate models suitable for thermal and EMC follow-on. We do not own a simulation tool stack — if your programme needs simulation we will tell you who to take the model to next.
How does the BOM stay in sync with the model?
Our workflow is single-source — the schematic, the 3D routing and the BOM are driven from one data layer. When the routing changes, the BOM changes. No spreadsheet to hand-update.
