Chamfergate in aisle 3D
Open source CAD in the browser (Solvespace)
Lightweight hero or buggy toy? Commenters go to war
TLDR: SolveSpace now runs in your browser as an experimental, offline-friendly CAD tool for small projects. The community is split between excitement over a fast, free option and frustration about bugs and missing basics, with debates spilling into “use FreeCAD,” “try Dune 3D,” and dreams of SolidWorks-level polish.
Open-source CAD app SolveSpace just strutted into your browser, and the crowd instantly split into camps. Fans love the lightweight feel and the “no install, runs offline” vibe—one user says it’s perfect for quick parts and laser-cutting services like SendCutSend and Oshcut. It’s a tiny tool with big ambition, compiled to run in your tab, and the devs admit it’s experimental, buggy, and best for small models.
Then the drama kicked in. Power users fired back that development has slowed and basic features are missing—cue “Chamfergate,” with critics pointing to a long-standing issue about beveled edges here. Another camp compares it to heavyweight commercial tools like SolidWorks, dreaming of an open “Parasolid-like” engine, while a separate thread veers into AI-with-CAD territory, with one commenter touting OpenSCAD as the best fit for large language models. And yes, there’s comedy: someone scrolls the mouse wheel and the model origin drifts off-screen, instantly becoming the day’s meme. Meanwhile, FreeCAD regulars shrug and say they’ll try it anyway because, hey, it’s free and in the browser. Verdict: a cool demo that might be a real tool—if you can live with quirks and a missing chamfer.
