Blender is world class, but the CAD softwares are leagues behind, unfortunately.

I wish there were open source alternatives to Autocad, but freecad is doing its own thing and as someone who uses Autocad as part of her career it's so much easier to keep a partition for when I need to throw something together than to learn how to make freecad work

Very different use case. I make parts to 3D print and CNC mill. Lots of brackets and other mechanical parts.
