Three upgrades to the Project Workflow: drop images and reference graphics onto the canvas, add backshells, wedge locks, cavity plugs and seals that roll into your BOM, and rotate connectors so wires leave the right face.
Export the connectors on your KiCad PCB straight into a Splice Project in one click. The new plugin brings in each board header with its pins and net-derived signals — ready for you to assign mating connectors and build the complete cable-harness document.
The Splice CAD MCP Server bridges AI agents directly to the Splice workspace. Instead of describing a design in text, agents execute operations — creating components, mapping pins, routing conductors — on the live canvas.
Design electrical systems top-down with Project Mode (beta): plan canvas with Layout and Schematic views, signals and nets, multi-page organization, assembly generation with auto-created ferrules. Plus box select, bulk connect, and wire anchor improvements.
Create manufacturing documentation with Layout View: multi-page drawings, assembly views, BOM tables, and annotations. Plus splice components, bundle accessories (heat shrink, zip ties), and Discord community.
Import connectors directly from KiCAD PCB and schematic files with automatic mating part matching, edit multiple components and wires at once with the Bulk Property Editor, collapse empty pins to simplify diagrams, and export cut lists and connection tables for manufacturing.
Add generic components and cables directly from the Harness Builder, export wire labels for heat-shrink printers, upload custom SVG/PNG graphics, and organize diagrams with bundle labels.
Generate cable harnesses programmatically with splice-py Python library, and embed interactive harness diagrams on your website with @splice-cad/embed JavaScript library.
New import capabilities including SVG and PNG/raster image support, plus manual preview bounds control with interactive drag and resize handles.
Expanded parts library with TE terminals and Weidmuller ferrules, JSON and WireViz import capabilities, and fixes for copy/paste, cable shields, and connector creator workflows.
Enhanced component creation with text labels and pin controls, visual wire search with color swatches, expanded striped wire library, and independent signal names per connection end.
Teams, per-harness sharing by email, role-based permissions, and usage limits. Create teams, invite members and share harnesses with others.
We renamed connectors to components with categories like circuit breakers, switches, and motors, added faster wire property editing from the sidebar or canvas, and introduced Bulk Connect for straight-through, crossover, and custom patterns.
New features include group selection and bulk operations in Connector Creator, a PDF Page Configurator for multi-page engineering drawings, and symmetric DB-15/DB-25 templates.
New features including command-based undo/redo, multi-select & group repositioning, copy/paste support, multiple connections per pin, and DB37/DB50 connector templates.
New features including bridged pins, enhanced wire sizing, WireViz compatibility, design notes, harness cloning, and expanded documentation.
