Hey there! As a 3D printer addict I do a lot of small parts in CAD to print and use around the house. Lately I've been exploring all sorts of CAD software since finding out there's a more around than just Fusion360 and Onshape so I started exploring what's out there and jotting down my impressions.
Hope this is not spam, just want to help people see what's around and help them pick!
I would also recommend checking out SALOME for 3D modeling. I’ve been using the shaper toolbox to create geometry for fluid simulations and it’s worked well for me. The shaper toolbox is parametric (as opposed to SALOME’s geometry toolbox which is not).
After you’ve created your geometry in shaper you switch to the mesh toolbox to create your stl file. I think there’s really good control over the triangle creations with SALOME. For example, you can specify edges and faces you want smaller triangles in (like around tight geometries, holes, etc). I’ve been able to get much higher quality stl files with this method than with freecad.
SALOME is free and open source software.
SALOME is definitely on my list along CAD Builder, which as far as I could see seems a more streamlined version of SALOME 9.09 focused on part modeling (at least from my 5 min quick look)
