    Fusion is CAD, while Blender is 3D modeling

    It's not the same goal. Autodesk is for engineering, blender is for animation/art. Both are great but they are not for the same job

    It's the most similar to Fusion 360 while still being free.

    FreeCad has been my go to since I left school, and the free student demo of solid works, as there are many packages you can add on to make it more customization. In my opinion, FreeCAD vs Solidworks is like Windows vs Linux, SW polished early with money, but given time, FreeCAD can find a huge market and be a serious competitor.

    Uses constrain sketch design and is a quite different interface from Fusion 360, but the essential core is pretty similar and an excellent alternative especially for linux users that don't want to mess with wine.

    Because fusion is gui/wysiwyg based, openscad is writing commands based.

    CaDoodle is most similar to TinkerCAD, but includes a timeline of modifications, like fusion, and tight integration to Sketch, Sculpt and Programmatic modules that rival Fusion in total capability.
