DiffCAD, a FreeCAD workbench to review model changes like code
I'd like to share a new workbench I've been working on called DiffCAD. Coming from a software engineering background, not having the ability to properly diff my CAD model changes was driving me crazy. This project scratches my own itch, and maybe someone elses', too! I'm open to feedback, ideas, and contributions. Cheers!

What it does
A FreeCAD workbench to track CAD model history and review changes using 3D and tree comparisons. - eblanshey/HistoryWorkbench
History Workbench helps you create CAD projects with confidence through simple version control: tracking iterations over time, reviewing in-progress work, and showing model changes as detailed 3D and parametric tree comparisons. Once you can review every iteration visually, it's hard to work any other way. History Workbench uses Git internally for version control, but Git knowledge is not required for normal use. The workbench intentionally replaces Git terminology with CAD-focused terms so that the workflow intuitively matches how CAD users think about model history.

DSLCad – a programming language and interpreter for building 3D models2023 · github.com · ▲198Hey HN. Over the last half a year I have been working on a 3D CAD programming language called DSLCAD. Today I am here to show my first release! It is heavily inspired by OpenSCAD which got me hooked on the idea of a CAD programming language and what it can do. Please let me know what you think. Ill be in the thread to answer any questions you may have.

Hello HN users, This is a CAD by code project I have been working on on my free time for more than year now. I built it with 3 goals in mind: - It should be familiar to CAD designers who have used other programs. Same workflow, same terminology. - Reduce the mental effort required to create models as much as possible. This is achieved by: - Provide live rendering and visual guidance as you type. - Allow the user to reference existing edges/faces on the scene instead of having to calculate everything. - Provide interactive mouse helpers for features that are hard to write by code: Only 3…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
