Next Generation Wire Harness Design

AI-native cloud CAD. The agent operates the design — not just reviews it. Describe the task in plain language and get production-ready drawings, BOMs and cut lists.

Is this you?

Wherever harnesses are designed, quoted or built

Harness shops & cable assemblers

Quote RFQs in hours, not days — from any input a customer sends.

OEM engineers

Machinery, electronics, appliances: fewer errors reach production.

Engineering bureaus & freelancers

Every client format readable; your automation is reusable.

Motorsport & custom builders

From words to a professional drawing — with a real shopping list.

Cable & harness factories

Your branded editor, your catalog, direct orders.

Regulated industries

Aerospace, defence, rail: on-prem AI inside your perimeter, named checkpoints and revision history for every change.

The Friday Afternoon RFQ

From a customer sketch to a quoted deliverable — in under an hour

An RFQ lands on your desk

A hand-drawn sketch, a photo, or a legacy PDF — the kind of request that used to cost you a day of redrawing.

AI digitizes the drawing

Attach the file to the AI agent. It extracts connectors, wires and colors into an editable LoomCAD schematic.

Real parts from DigiKey

Search and place actual components with part numbers, contacts and product images — no manual data entry.

Manufacturing data falls out

BOM, wire list and wire cut list are generated from the same design — export to PDF or Excel in one click.

Quote sent before the weekend

A professional drawing package and priced BOM go back to the customer the same afternoon.

LoomCAD Magic

Automate with Natural Language

Describe the task in plain language and the AI agent turns it into a runnable script — reviewed by you, executed in a sandbox, with an automatic checkpoint created before every run so one click undoes anything.

User:
Draw connectors J1 and J2, 2 pins for each, connect by bundle, connect also relevant pins by wires - red and green
LoomCAD:
Prevent Errors Before Production
Wire gauge vs. contact rating mismatches
Incompatible or missing contact types
Missing part numbers and component properties
Dangling wires and naming conflicts

Prevent Errors Before Production

Ask the AI to validate the design and it runs a structured rule check across the whole project — catching the problems that are expensive to find on the shop floor.

Digitize Legacy Drawings

Attach a PDF or photo of an existing drawing and the AI extracts connectors, wires and colors into an interactive LoomCAD schematic you can edit immediately.

Real Components, Real Data

Connected to the part catalogs your purchasing team already uses

DigiKey

Search the DigiKey catalog inside LoomCAD, place parts with real part numbers, and pull substitutions and associated contacts without leaving the canvas.

Octopart

Fetch component data and availability across distributors through the Octopart network — one more source for accurate, current part information.

Product images become drawings

When you import a part, its product photo is placed on the sheet as the connector view — your drawing looks like the real harness.

From Drawing to Shop Floor

Every design generates its manufacturing data automatically

Bill of Materials

Every part, quantity and manufacturer number, always in sync with the drawing

Wire List

From/to, color, gauge and length for every wire in the design

Wire Cut List

Grouped cut lengths with margin included — ready for the cutting bench

Connector Summary

All connectors with pin counts and contacts for kitting and assembly

PDF
Excel
CSV
SVG

Not a picture of a harness — a project that ships production documents.

AI You Can Supervise

The agent is powerful because you stay in control

You decide what the AI sees

Context badges give the AI access to exactly the parts of your project you choose — nothing is shared implicitly.

Every action is a script you can read

The AI does not silently mutate your design. It writes a script, you see it, and it runs in a sandboxed environment.

Every run has an undo

A named revision checkpoint is created automatically before each AI script runs — restore the previous state with one click.

Growing Complexity in Modern Manufacturing

Wire harness design has become increasingly complex across all industries

3,000+

wires in a modern car — close to 40 harnesses and roughly 700 connectors

4 km · 60 kg

laid end to end, one car's wiring stretches past 4 km and weighs about 60 kg

55 → 3,000

wires in a family car: 1948 vs today. The complexity exploded — everyday tooling didn't.

Figures: Siemens / Mentor Graphics industry publications.

Modern vehicles contain up to 40 harnesses with ~3,000 wires and 700 connectors

Home appliances, HVAC systems — each product requires precise wiring design

Agricultural and heavy machinery demand robust, reliable electrical systems

Legacy desktop tools create bottlenecks across all manufacturing sectors

The Future of Engineering

Digital transformation in manufacturing is not the future, it's happening now.

LoomCAD is your gateway to this future.
