Rant Warning, plus a solution:
Let me count the ways I despise the demise of Sketchup as a common-man's 3D tool.
Firstly, the freeware version is no longer licensable for commercial use, now that the software belongs to Trimble. Fair. No grouses from me there. Some other creators may have problems with this though.
Secondly, the 2014 release of Sketch Make (the freeware version), is using Ruby 2.0. Innovation for improvement is a good thing, but old scripts which work in Sketchup 8 no longer work in Sketchup Make 2014. BAD. There are plenty of useful and helpful ruby plug-ins for SU8. I expect that it is likely no further development will take place for these.
Trimble is focusing on other geo-mapping / geo-modelling strategies to accomplish a different goal from Google. No surprises over the change in strategic development and purposing of Sketchup Make 2014.
BUT I HAVE A CUNNING PLAN. HU HU HU HU. I need OBJ files. I use Shade 3D for Unity. It is free for non-commercial use. I can export to OBJ files using that. Oh wait, it can also import existing SKP files. Ah Ha !
Depending on whether the now much less useful Sketchup Make 2014 can support my 3D modelling needs, I can save out to SKP and import into Shade 3D for Unity, then export as OBJ. NICE.
Which means I can also grab SKPs from 3DWarehouse and import them into Shade 3D for Unity. LA LA LA.
