If you have an older version of sketchup (2014, 2015, 2016), and you can’t open a more recent file of Sketchup (like 2017) – for example because your computer doesn’t support a newer version of sketchup,
you can convert online your file by uploading in Google Warehouse. Unluckily there are not all the versions available, but it is a useful trick.
After the upload, you can download it in multiple versions.

FOR THE OPPOSITE: FROM 2017 TO 2014
Do you want to save in an older version?

Click on File -> Save AS -> and choose the version you need.
