Hi there, brand new to SketchUp Free/Web… so I tried to find official videos through the link at the buttom left ? circle. When clicking I reach a page which says "The requested page could not be found. " - what is the correct link please.
Thanks 
It appears they are revamping the help pages. Everything looks different. You can start here, though. I expect in the next few days they will get links fixed and everything will be fine.
Cheers.
