Dune 3D is new a parametric 3D CAD application that supports STEP import/export, fillets and chamfers.

So why another open-source 3D CAD application when FreeCAD and Solvespace exist? My primary use case for 3D CAD is designing 3D-printed enclosures for my electronics projects. I often found myself procrastinating designing the enclosure and attributed that to my dissatisfaction with the available open source 3D CAD applications.

While FreeCAD technically does everything I need, the way it’s implemented isn’t quite to my liking. My biggest pain points with it are the modal sketcher that only works in 2D, no constraints in 3D for extrusions and the perils of referencing things in the design.

It should work on any reasonably up-to-date Linux distro, various BSDs and Windows using MSYS2.
