And as you said previously, current CAD tools are slow to improve, and part of the reason is because of using kernels first built in the 1980s, and projects like Shapr3D and Plasticity both hit limitations of their existing kernels and switched to Parasolid when their project got bigger, and OCCT's per entity tolerance issue is pretty well know by now.\nOn another topic, getting a plate with thousands of holes to mesh in under a second is some serious performance, and I do agree with your conclusion that most CAD apps are slow not because of programming language but because accurate NURBS math is inherently slow, but their is also the issues with the 2D constraint solver and fillet/boolean algorithms too. Happy to talk more about the geometry kernel stuff too.","parent_id":50441350,"replies_count":1,"hn_url":"https://news.ycombinator.com/item?id=50449784"},{"id":50448451,"author":"sincman","created_at":"2026-11-11T00:51:06.000Z","text":"What is the geometry kernel?
