I just transferred my licence to SketchUp 2017 from 2016. But after starting to try 2017 the first thing that i figure out is the program has a bug while trying to make group an object. Let me try to explain more.
I have a exploded object and i try to rotate it with CTRL key to copy too. And then i figure that the object is not a group. Then I cancelled the rotation and push the key “Z” which i use for “make group” for grouping the already selected object. Then the program is giving a bug splat and closing.
