Hi, for your information the plugin SU2XL works on previous versions of SketchUp (from SU08 till SU2017).
You can download it on the Extension Warenhouse:
https://extensions.sketchup.com/en/content/su2xl-0
or on the http://www.wisext.com site:
http://www.wisext.com (a windows installer is available to install easily the tool).
