Collada support is critical for me, it is the whole reason why i am using sketchup. For better or worse, the web ‘game’ SecondLife has moved heavily to mesh and only supports Collada DAE files. Given SecondLife has many millions of users, almost never less that 30,000 online at any given instant, Sketchup really needs to have first-class support of DAE to be part of that. Right now, Sketchup-2016 exports BROKEN collada files that SecondLife rejects with a parsing error and even freebie 3D-Build says has errors (but is able to fix and mostly display the broken Sketchup DAE). So for now, I( have had to move to using the complex ‘Blender’ tool since its Collada DAE files do work in SecondLife.
