Second this. Since Opus 4.6 there's been a very noticeable bump in accuracy at just doing FreeCAD+Python or OpenSCAD code, usually one-shots things with basically described geometry.

Recently, Sonnet 5.5 got quite good, too, but not at the level of Opus/Fable for complex geometry

Disclaimer: I use it for very precise 3D printing, not woodwork.
