SketchUp 2017 is not saving the latest changes. I have to delete what I want, then Save, then move the model around and then Save and maybe save it again before it will show the right picture in Explorer and have the right file size.
Really what you are saying is that File Explorer is not updating the thumbnail?
Thanks, I did not consider that it might be a File Explorer problem
Would it be File Explorer if the file size is also not updating though
