Ok, thank you for making me dig john.
I checked the Ruby console, did screen captures of 2014, 2015 and 2016. Checked the file locations and did screen captures of all three as well. Then I checked (after all that) the extensions window in System Preferences and the 3DxSketchUp extension was unchecked.
Sorry for the bother, thanks again for making me dig.
Runs away happy. π
