3DPrinting is a place where makers of all skill levels and walks of life can learn about and discuss 3D printing and development of 3D printed parts and devices.
The r/functionalprint community is now located at: !functionalprint@kbin.social or !functionalprint@fedia.io
There are CAD communities available at: !cad@lemmy.world or !freecad@lemmy.ml

Got this email from Autodesk that Fusion is increasing their annual price by a huge amount. I subbed for 1 year a couple years ago for I think $380. Then I was able to get an educational sub after that. Fusion is still the cheapest CAD software out there, not including the free stuff like FreeCAD, but still, this price increase is massive.
It should be noted that it's still free to use for personal use minus the extra features.
Uhm, what about Blender?
Blender is not designed as a CAD software. It is for 3d modeling. So you would use Blender to make graphics for a video game, or a 3d movie.
CAD is more for designing things to be made outside of a computer, so 3d printing, CNC or stuff like that.
Blender doesn't consider the object as a whole, and can leave holes that a CAD setup would handle.
You can still use blender though if you know how to model in it already. Just don't leave holes and you will be fine. I use that for a lot of 3d prints I make just because I am already comfortable with it.
Blender workflow is very different to a CAD workflow. It's ok for small things, but if you need to design some complex functional parts with tight tolerances, you will waste a lot of time in Blender.
blender can be used as cad software, but for any practical application, you want parametric design.
