Sketchup version for books

I went to book store to look for a sketchup book… I have installed 2016 and works good…
the only book i found that was close was sketchup 2014 for dummies…

are the commands similar? I know when i used draw program years ago and came back the tools/menu’s screwed me up big time…

what version are similar so i dont get a useless book…
thnx

The keyboard commands have not changed in years.
Download the SketchUp 2016 Quick Ref Card for commands:

The main difference, for SketchUp 2016, is addition of the Microsoft Tray system added for the SketchUp inspector toolwindows. See:

Start with the online User Guide:

… and the online tutorials:

Following @DanRathbun suggestion, I would start with videos, you will have a better learning experience with watching people using SketchUp than with reading static books…
