24 alternatives to 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…

AI CAD Harness▲101Hi HN, I'm Zach, one of the co-founders of Adam (https://adam.new). We've been on HN twice before with text-to-CAD/3D experiments [1][2]. The honest takeaway from those threads: prompt-to-3D model web apps are fun, but serious mechanical engineers don't want a black box that spits out an STL. They want help inside the CAD tool they already use, with full visibility and control over the feature tree. So we built that. Adam is now a harness that integrates directly with your CAD. It reads your parts, understands the existing feature tree, and edits it for you agentically. We are…

I’ve been heads-down for the last month or so working on a new spline, and now I’m excited to show it to the world. It is a continuation of the Spiro work I did for my PhD thesis, and solves most of the problems that held that back from wider popularity.

I'm currently developing Chili3D, an open-source, browser-based 3D CAD application. By compiling OpenCascade to WebAssembly and integrating Three.js, Chili3D delivers near-native performance for powerful online modeling, editing, and rendering—all without local installation. Access it here: https://github.com/xiangechen/chili3d Features: Modeling Tools: Create basic shapes (boxes, cylinders, cones, etc.), 2D sketches (lines, arcs, circles, etc.), and perform advanced operations (boolean operations, extrusion, revolution, etc.). Snapping and Tracking: Precisely snap to…

Hi everyone started this project a year ago to generate the CAD for a Jet Engine Axial Compressor. I am now open sourcing this tool that can take in a JSON file with specs and generate the CAD assembly. Still has a lot of work to improve designs but there isn't anything the Open Source community can't accomplish!
