Show HN: Splice – CAD for Cable Harnesses and Electrical Assemblies 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://ift.tt/1xVA3Gu ) 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 Try it out, no signup: https://ift.tt/2j4bse1 Docs & tutorials: https://ift.tt/jBLZWtK https://splice-cad.com August 22, 2025 at 01:10AM
