You end up having to click and enter so many numbers if you need exact dimensions, so I'm planning on switching to cadquery.
It would be cool to make a framework for modifying cadquery code with natural language, for example "make box 1 and box 1 flush" or "create two concentric semi-spheres and subtract the smaller one from the larger one"
But idk, maybe once you're fast at fusion this kinda stuff is faster to hotkey than speak
