FluidCAD – Parametric CAD with JavaScript▲160
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…

An open source tool to generate Jet Engine compressors▲35
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!

My tool generates 3D objects composed of separate, functional parts▲5
I've noticed all 3D AI generators create monlithic blobs that are impossible to edit. So, alongwith a friend, I built this project where you can generate 3D objects with separate, editable parts. I'm looking for community feedback. The tool is free, but you'll have to BYOK. It uses models like Gemini, Claude or chatGPT to generate a Blender construction script. Basically the output is not merely geometry. It's the procedure that built it, plus the asset itself. This means you can actually go in and edit the "kit of parts" afterwards, instead of starting over.
