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
