I just noticed that the SketchUp version you have is <2016.
Therefore "Persistent IDs" cannot be used - these are needed to circumvent the lost IDs during newer SketchUp processes...
Oh sorry, i wasn't aware of that.
Thanks for the update. It's working great now! Very cool. 
Could you put it into the right click menu to the other export options?
Btw. is it possible to configure the right click menu? The list is getting very long and there are some entries that i never use. I somehow remember that this wasn't possible and you had to change it in the plugin code. If this is the case, is there a single command that can be commented out to deactivate it without generating problems or is it more complex?

) i don't really like those arrows. I would prefer strokes. And the text aligned to the dimension line, like in Revit for example...
It would be great if Trimble would show only a fraction of this speed and transparency in their development.
