Re: Future ARM laptops
Being able to drag around the 3D model of sprocket (fine, three sprockets) in a browser window may be good enough for the 3D-printer-happy "maker" generation but is not something I would call CAD software. Meanwhile out here in the real world even proper, compiled executables running on desktop / laptop class hardware die a thousand deaths as soon as you try dragging a mere component of an assembly in an ever-so-slightly non-trivial design in a parametric CAD.
The open source one I prefer is basically shitting bricks with a single assembly loaded simply because it happens to unluckily fall on the wrong end of the O(n^x) complexity involved in continually re-evaluating moving geometry - badly enough that it managed to get me to try to figure out whether that can be helped at all; and just so nobody gets the wrong idea, as anyone following the construction of the Marble Machine X should well know, its designer hit a brick wall not long ago splatting against the limits of Autodesk Fusion 360 running on real-world hardware.
So 'scuze me if I need to lay down to properly laugh at any suggestions that browser-based CAD running on an ARM-class CPU is "good enough" in any sense of the word.
