I've been using Astra to just create things in Blender. It's great.

Kill the scroll jacking. It's a sign you're on Windows.

CAD is a different beast than mesh modeling. For product design you need a parametric model that can have precise dimensions and is constructed mathematically step by step. Mesh modeling is just moving a pile of triangles around in a very imprecise way. Works fine for 3D printing or digital assets, but if you want something that can be manufactured that's not good enough. And there isn't a good way to go from STL -> Parametric CAD so there's still room for a product here.

I gave some very bad sketch made in jspaint to Astra, plus some text instructions, and I got back some clean STL file and a beautiful 3D render.

It even made a second STL file with the same model rotated for 3D printing.

I remember all those hours on SolidWorks many years ago, and now you can just speak and present bad drawings to the computer, and it does it okay.

Exactly. I just give Astra an image such as furniture, and it creates an 3D reproduction in Blender. You don’t even need computer use. Codex and Blender’s scripting engine is enough.

Are you hooking it up to blender via some MCP or are you just creating files and opening in blender?

I've had decent success getting Claude Opus to design models using the python cadquery library, and then I can import the step file to fusion 360 to make any changes I want afterwards.
