About Dune3d
Dune 3D is 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.
