This update expands our parts library with commonly requested terminal types, adds import capabilities for JSON and WireViz formats, and resolves several reported issues.
Library Additions
TE Connectivity Quick Disconnects and Ring Terminals
We've added TE Connectivity terminals to the parts library:
- Quick Disconnects: Industry-standard insulated and non-insulated quick disconnect terminals in various sizes (0.110", 0.187", 0.250")
- Ring Terminals: Range of ring terminals for secure bolted connections with multiple wire gauge compatibility
Search for "quickdisconnect" or "ring" in the Components Library to access these parts.
Weidmuller Ferrules
The library now includes Weidmuller's ferrule lineup:
- Wire end ferrules for wire termination
- Full wire gauge coverage from 26 AWG to 10 AWG
Search for "ferrule" or "weidmuller" in the Components Library.
New Features
JSON Import
You can now import harness designs from JSON files:
- Export to JSON via the Download menu for offline storage or version control
- Import JSON to restore designs, share with collaborators, or migrate between environments
- Full fidelity: All design elements including components, wires, cables, positions, and settings are preserved
Access JSON import via Download & Upload -> Data Import/Export -> Import from JSON.
WireViz YAML Import (Beta)
We've added initial support for importing WireViz YAML files:
- Import basic harness structures including connectors, cables, and connections
- Automatic component matching against Splice's parts library where possible
- Wire and cable specifications are mapped to equivalent parts
Current limitations:
- Custom connector graphics from WireViz are not yet imported
- WireViz native designs may not import correctly
This is an early-stage feature - we're actively working to improve compatibility and coverage. Feedback is welcome!
Access WireViz import via Download & Upload → Data Import/Export → Import from WireViz in the Harness Builder.
Bug Fixes & Improvements
- Copy/Paste with Wired Components: Fixed - copying and pasting connectors or cables with existing wire connections no longer generates errors on save.
- Cable Shield Visibility: Fixed - cable shields are now visible on the canvas as dashed black lines.
- Cable Length Editor: Fixed - the cable length field now properly saves values.
- Flying Lead Positioning: Improved - flying leads now generate in unoccupied space instead of partially underneath cable components, making them easier to select and position.
- Connector Creator Handle Scaling: Improved - shape handles in the Connector Creator no longer scale with zoom level—they remain a consistent size for easier manipulation at any zoom factor.
- Clear Harness Button: Added - a dedicated "New Harness" button is now available in the bottom toolbar for quick access to creating blank designs (previously only accessible via right-click context menu).
