I first posted Splice CAD as an in-browser tool for making cable harnesses.

Since then it’s grown in both features and scope — the direction is moving from “harness-only” toward a lightweight CAD for wiring and electrical assemblies. New functionality includes:

Editing Enhancements

- Full undo/redo to easily restore editor state

- Multi-select & group actions to move, delete, and add components

- Bulk connect tool to create straight-through, crossover, or custom wiring patterns quickly

- Multiple connections per pin allow for daisy chains, etc.

Documentation Additions

- Multi-page PDF configurator to add A2, A3, or A4 pages for engineering drawing downloads

- WireViz YAML export (generate WireViz diagrams directly: https://www.danielrojas.net/projects/wireviz)

Library and Component Additions

- Expanded beyond harnesses to include categories for more applications: connectors, cables, breakers, fuses, switches, motors, power supplies

- Magic MPN button in the Component Creator to auto-fill specs from part numbers

This is awesome.

What’s your plan for pricing?

In my opinion: you should bundle this as an offline electron app that can save to the filesystem and get integrated into existing PLM. and/or sell a team plan that offers cloud design & library sync

… and partner with that YC company doing wire harness machines for a “buy now” button

This looks great and well designed.

If you want a bigger parts library, let us know at Volition:

It's a very well-designed tool. Great job.

Is there a way to add our own internal part numbers corresponding to manufacture's part number?

Can individual wires have different wire lengths?

Are there any features if when used won't render properly in wireviz?

Minor annoyance: Scrolling this webpage on iOS, when I reach certain scroll positions, videos randomly open in fullscreen even if I didn't tap on anything.

I don't understand what I'm looking at ...

Does this let you build like arbitrary wire bundles and then choose your own end pieces like the ones on an ATX power supply?

Can it document modular synthesizer patch configurations?

Fuck yes
